The purpose of this homework is to write an image filtering function to apply on input images. Image filtering (or convolution) is a fundamental image processing tool to modify the image with some smoothing or sharpening affect. You will be writing your own function to implement image filtering from scratch. More specifically, you will implement filter( ) function should conform to the following:
(1) support grayscale images,
(2) support arbitrarily shaped filters where both dimensions are odd (e.g., 3 × 3 filters, 5 × 5 filters),
(3) pad the input image with the same pixels as in the outer row and columns, and
(4) return a filtered image which is the same resolution as the input image.
You should read a color image and then convert it to grayscale. Then define different types of smoothing and sharpening filters such as box, sobel, etc. Before you apply the filter on the image matrix, apply padding operation on the image so that after filtering, the output filtered image resolution remains the same. (Please refer to the end the basic image processing notebook file that you used for first two labs to see how you can pad an image)
Then you should use nested loops (two for loops for row and column) for filtering operation by matrix multiplication and addition (using image window and filter). Once filtering is completed, display the filtered image.
Please use any image for experiment.
Here is information on image filtering in spatial and frequency domains.Image filtering in the spatial domain involves applying a filter mask to an image in the time domain to obtain a filtered image.
The filter mask or kernel is a small matrix used to modify the pixel values in the image. Common types of filters include the Box filter, Gaussian filter, and Sobel filter.
To apply image filtering in the spatial domain, one can follow the steps mentioned in the prompt, such as converting the image to grayscale, defining a filter, padding the image, and using nested loops to apply the filter.

You have defined two classes in Python. These classes also have constructor methods. In the first of these constructor methods, you have defined the variable "marca" twice. I fixed a typo in the "adicionar_item" method in the second class. I fixed the if-else block structure in the "remover_item" method.

Trace coding below
a = 1
b = 2
c = 5
while a < c
a = a + 1
b = b + c
endwhile
output a, b, c
Answer:
Explanation:
Initially, a is assigned the value 1, b is assigned the value 2, and c is assigned the value 5. The while loop is entered because a (1) is less than c (5).
In the first iteration of the while loop:
a is incremented by 1, so a becomes 2.
b is incremented by c (5), so b becomes 7.
In the second iteration of the while loop:
a is incremented by 1, so a becomes 3.
b is incremented by c (5), so b becomes 12.
In the third iteration of the while loop:
a is incremented by 1, so a becomes 4.
b is incremented by c (5), so b becomes 17.
In the fourth iteration of the while loop:
a is incremented by 1, so a becomes 5.
b is incremented by c (5), so b becomes 22.
At this point, the while loop is exited because a (5) is no longer less than c (5).
The output of the program will be:
5
22

what is the first computer?
Answer:
The first computer was called the "Atanasoff-Berry Computer" (ABC), which was developed by John Atanasoff and Clifford Berry in the late 1930s and early 1940s. The ABC was an electronic computer that used binary digits (bits) to perform calculations, and it was designed to solve systems of linear equations. While the ABC was not a general-purpose computer, it represented a major milestone in the development of electronic computing and laid the groundwork for later computer designs.

Like any other processor, a graphics processor needs
a.AGP.
b.HDMI.
c.GPU
d.RAM.
Answer: c. GPU (Graphics Processing Unit) is the correct answer.
Explanation: A graphics processor is a specialized type of processor designed to handle the complex calculations required for rendering graphics and images. It is the primary component responsible for producing the images you see on your computer screen. While AGP (Accelerated Graphics Port) and HDMI (High-Definition Multimedia Interface) are both types of interfaces used to connect a graphics card to a computer system, they are not necessary for a graphics processor to function. RAM (Random Access Memory) is important for overall system performance, but it is not a requirement specifically for a graphics processor.
Create a Java application using arrays that sorts a list of integers in descending order. For example, if an array has values 106, 33, 69, 52, 17 your program should have an array with 106, 69, 52, 33, 17 in it. It is important that these integers be read from the keyboard. Implement the following methods – getIntegers, printArray and sortIntegers. • getIntegers returns an array of entered integers from the keyboard. • printArray prints out the contents of the array • sortIntegers should sort the array and return a new array contained the sorted numbers
Answer: import java.util.Arrays;
import java.util.Scanner;
public class SortIntegers {
public static void main(String[] args) {
int[] originalArray = getIntegers();
System.out.print("Original array: ");
printArray(originalArray);
int[] sortedArray = sortIntegers(originalArray);
System.out.print("Sorted array in descending order: ");
printArray(sortedArray);
}
public static int[] getIntegers() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter the number of integers: ");
int n = scanner.nextInt();
int[] array = new int[n];
System.out.print("Enter " + n + " integers: ");
for (int i = 0; i < n; i++) {
array[i] = scanner.nextInt();
}
return array;
}
public static void printArray(int[] array) {
for (int i = 0; i < array.length; i++) {
System.out.print(array[i] + " ");
}
System.out.println();
}
public static int[] sortIntegers(int[] array) {
int[] sortedArray = Arrays.copyOf(array, array.length);
Arrays.sort(sortedArray);
for (int i = 0; i < sortedArray.length / 2; i++) {
int temp = sortedArray[i];
sortedArray[i] = sortedArray[sortedArray.length - 1 - i];
sortedArray[sortedArray.length - 1 - i] = temp;
}
return sortedArray;
}
}
Explanation: The following elucidates the operational mechanism of the program:
The method named getIntegers prompts the user to enter the desired quantity of integers to be inputted, followed by the inputting of integers from the keyboard, with the resultant integers being returned as an array data structure.
The printArray function accepts an array as an argument and outputs the array's elements.
The sorterIntegers function generates a duplicate of the input array through the usage of the Arrays.copyOf method, proceeds to sort this array in ascending order utilizing the Arrays.sort method, and subsequently performs a fundamental swap operation to invert the placement of the elements, thereby achieving the targeted descending order. Subsequent to the sorting process, the array is subsequently relinquished.
In the principal procedure, the software invokes getIntegers to retrieve the input array, produces its contents with printArray, sorts the array via sortIntegers, and displays the ordered array using printArray.

Explanation:
Overview As you are preparing for your final text game project submission, the use of dictionaries, decision branching, and loops will be an important part of your solution. This milestone will help guide you through the steps of moving from your pseudocode or flowchart to code within the PyCharm integrated development environment (IDE). You will be working with the same text-based game scenario from Projects One and Two. In this milestone, you will develop code for a simplified version of the sample dragon-themed game. The simplified version involves moving between a few rooms and being able to exit the game with an “exit” command. In the simplified version, there are no items, inventory, or villain. Developing this simplified version of the game supports an important programming strategy: working on code in small iterations at a time. Completing this milestone will give you a head start on your work to complete the game for Project Two. Prompt For this milestone, you will be submitting a working draft of the code for a simplified version of the text-based game that you are developing for Project Two. You will focus on displaying how a room dictionary works with the “move” commands. This will include the if, else, and elif statements that move the adventurer from one room to another. Before beginning this milestone, it is important to understand the required functionality for this simplified version of the game. The game should prompt the player to enter commands to either move between rooms or exit the game. Review the Milestone Simplified Dragon Text Game Video and the Milestone Simplified Text Game Flowchart to see an example of the simplified version of the game. A video transсrіpt is available: Transсrіpt for Milestone Simplified Dragon Text Game Video. IMPORTANT: The “Move Between Rooms” process in the Milestone Simplified Text Game Flowchart is intentionally vague. You designed a more detailed flowchart or pseudocode for this process as a part of your work on Project One. Think about how your design will fit into this larger flowchart. In PyCharm, create a new code file titled “ModuleSixMilestone.py.” At the top of the file, include a comment with your name. As you develop your code, you must use industry standard best practices, including in-line comments and appropriate naming conventions, to enhance the readability and maintainability of the code. Next, copy the following dictionary into your PY file. This dictionary links rooms to one another and will be used to store all possible moves per room, in order to properly validate player commands (input). This will allow the player to move only between rooms that are linked. Note: For this milestone, you are being given a dictionary and map for a simplified version of the dragon-themed game. Make sure to read the code carefully so that you understand how it works. In Project Two, you will create your own dictionary based on your designs. #A dictionary for the simplified dragon text game #The dictionary links a room to other rooms. rooms ＝ { ′Great Hall′: {′South′: ′Bedroom′}, ′Bedroom′: {′North′: ′Great Hall′, ′East′: ′Cellar′}, ′Cellar′: {′West′: ′Bedroom′} } A portion of the map for the Dragon Text Game showing the Great Hall, Bedroom, and Cellar, with arrows indicating the directions the player can move between them. The Cellar is to the East of the Bedroom, which is to the South of the Great Hall. Next, you will develop code to meet the required functionality, by prompting the player to enter commands to move between the rooms or exit the game. To achieve this, you must develop the following: A gameplay loop that includes: Output that displays the room the player is currently in Decision branching that tells the game how to handle the different commands. The commands can be to either move between rooms (such as go North, South, East, or West) or exit. If the player enters a valid “move” command, the game should use the dictionary to move them into the new room. If the player enters “exit,” the game should set their room to a room called “exit.” If the player enters an invalid command, the game should output an error message to the player (input validation). A way to end the gameplay loop once the player is in the “exit” room TIP: Use the pseudocode or flowchart that you designed in Step #4 of Project One to help you develop your code. As you develop, you should debug your code to minimize errors and enhance functionality. After you have developed all of your code, be sure to run the code to test and make sure it is working correctly. What happens if the player enters a valid direction? Does the game move them to the correct room? What happens if the player enters an invalid direction? Does the game provide the correct output? Can the player exit the game? Guidelines for Submission Submit your “ModuleSixAssignment.py” file. Be sure to include your name in a comment at the top of the code file.

# A dictionary for the simplified dragon text game
# The dictionary links a room to other rooms.
rooms = {
'Great Hall': {'South': 'Bedroom'},
'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
'Cellar': {'West': 'Bedroom'}
}
# Set the player's starting room
current_room = 'Great Hall'
# Output the player's starting room
print('You are in the', current_room)
# Game loop
while True:
# Prompt the player for input
command = input('What would you like to do? ')
# Split the input into a list of words
words = command.split()
# If the player wants to move
if words[0].lower() == 'go':
# Check if the player entered a valid direction for the current room
if words[1].title() in rooms[current_room]:
# Move the player to the new room
current_room = rooms[current_room][words[1].title()]
# Output the new room
print('You are in the', current_room)
else:
# Output an error message for invalid input
print('You cannot go that way.')
# If the player wants to exit the game
elif words[0].lower() == 'exit':
# Set the player's room to exit
current_room = 'exit'
# End the game loop
break
else:
# Output an error message for invalid input
print('Invalid command.')
# Output a farewell message
print('Thank you for playing the game!')
If the player enters a valid direction, the game will move them to the correct room as specified in the dictionary. For example, if the player is in the Great Hall and enters "South," they will be moved to the Bedroom. If the player enters an invalid direction, the game should output an error message to the player, letting them know that their command was not recognized. If the player enters "exit," the game should set their current room to "exit," which will end the gameplay loop and exit the game.Hope this helps!

A.
The user will have to navigate every page sequentially.
B.
The website will have categories with sub-categories.
C.
The user can visit any page from any other page.
D.
The website is structured with a central home page.
Chris is creating a storyboard for an author's website using a hierarchical structure. In this case, the correct statement regarding the website he is creating would be: "The website will have categories with sub-categories."
The correct answer is option B.
A hierarchical structure organizes information into a top-down structure, with the main categories being subdivided into smaller, related sub-categories. This allows for easy navigation and organization of content, making it user-friendly.
The other options do not accurately describe a hierarchical structure: navigating pages sequentially refers to a linear structure, visiting any page from any other page implies a web-like structure, and a central home page is a characteristic of many website structures, not specifically hierarchical.
In summary, the true statement about Chris's website with a hierarchical structure is that it will have categories with sub-categories, providing an organized and user-friendly experience for visitors.
Therefore, option B is correct.

Primary keys, foreign keys, and references are all important concepts in relational database management systems (RDBMS).
How to explain the informationA primary key is a column or set of columns in a table that uniquely identifies each row in that table. It is used to enforce the integrity of the data by ensuring that each row is unique and that it can be referenced by other tables. Primary keys are typically used as the basis for relationships between tables.
A foreign key is a column or set of columns in a table that refers to the primary key of another table. It is used to establish a relationship between two tables, where the foreign key in one table refers to the primary key in another table. This allows you to link related data between tables in a database.
A reference is a term used to describe the relationship between two tables in a database. When one table contains a foreign key that refers to the primary key of another table, we say that the first table has a reference to the second table. The reference allows you to join the two tables together in order to retrieve related data.
In summary, primary keys are used to uniquely identify rows in a table, foreign keys are used to link data between tables, and references describe the relationships between tables in a database.

In group assignments, it is important for all individuals in the group to be transparent about their contributions to the project because this increases the quality of the overall work process. (Principle 2.1)
Title: The ACM Code of Ethics and Its Impact on the Behavior of Undergraduate Computing Students
What is the judgement?Introduction:
The field of computing encompasses a wide range of technologies and applications, and professionals in this field are expected to adhere to high standards of ethical and professional conduct. The ACM (Association for Computing Machinery) Code of Ethics and Professional Conduct serves as a guiding framework for computing professionals, providing principles and guidelines to make informed judgments and decisions in their practice. In this paper, we will explore how the ACM Code of Ethics can shape the behavior of undergraduate computing students and influence their personal actions.
Professional Responsibilities and Informed Judgments:
As an undergraduate computing student, it is essential to understand and demonstrate professional responsibilities and informed judgments in computing practice. The ACM Code of Ethics, with its eight principles, provides guidance on how computing professionals should act ethically and responsibly in their practice. For example, Principle 1.1 of the Code emphasizes the importance of contributing to society by using computing resources in a beneficial and socially responsible manner. An undergraduate computing student should understand the implications of their work on society and strive to use their computing skills to make a positive impact.
Furthermore, Principle 1.2 of the Code highlights the need to avoid harm to others in computing practice.

Principle 2.2 of the Code emphasizes the need to respect the privacy of others and protect their personal information. As an undergraduate computing student, it is essential to understand and comply with relevant laws and regulations related to data privacy, such as the General Data Protection Regulation (GDPR) in Europe or the Health Insurance Portability and Accountability Act (HIPAA) in the United States. Students should also be mindful of ethical considerations related to data privacy, such as obtaining proper consent before collecting or using personal data.
In addition, Principle 2.6 of the Code highlights the importance of respecting intellectual property rights. Undergraduate computing students should understand the implications of intellectual property laws, such as copyright, patents, and trademarks, and should avoid any actions that could infringe upon these rights. This includes properly citing and referencing sources in their work, obtaining proper permissions for using copyrighted materials, and respecting the intellectual property of others.
Lastly, Personal Actions and Behavior:
The ACM Code of Ethics also has a significant impact on the personal actions and behavior of undergraduate computing students. For example, Principle 3.1 of the Code emphasizes the importance of maintaining integrity and honesty in computing practice. Students should strive to be honest in their academic work, such as submitting their own original work and giving credit to others for their contributions. Students should also be truthful in their interactions with colleagues, clients, and other stakeholders in their computing practice, and should avoid any actions that could compromise their integrity.
