Using the Python documentation as a guide, create a program that loads the image, filters three copies of it, and saves the result. Note: You will need to create the three filters using the filter() method. Include multiple filters on at least two of your variants. One of your variants must apply a single filter multiple times with the use of a loop. For example, the top right image above uses a loop to blur the image 2 times (what if we did it 100 times?). One of your images must apply at least two different filters to the same image. In the example image, the bottom right image includes a a filter to smooth the image and then edge enhance them.arrow_forward
- Write up Java source code for compiling and execution of program below. There is a very simple solution to keeping Tic-tac-toe fresh and interesting, though, and it has been thought up by a group of mathematicians. It’s being called Ultimate Tic-tac-toe and simply embeds a Tic-tac-toe board in each of the nine squares of the original game. Now instead of just winning the main board, you also need to win each of the smaller boards first until you have a line of three. New Rule: You can only place a mark on the board determined by the position of your opponent’s last placed mark. So, if they put an X or O in the top right corner of a square, your next move must occur in the top right board. By adding that rule the game is no longer about winning a single board, it’s about tactically managing up to 9 games at once and plotting ahead. You still win by marking three squares in a row, but that now involves winning three games.  The effects of the New Rule: 1: Your opponent can force you to…arrow_forwardPlease can you help me solve this problem in Python. Darkening an image requires adjusting its pixels toward black as a limit, whereas lightening an image requires adjusting them toward white as a limit. Because black is RGB (0, 0, 0) and white is RGB (255, 255, 255), adjusting the three RGB values of each pixel by the same amount in either direction will have the desired effect. Of course, the algorithms must avoid exceeding either limit during the adjustments. Lightening and darkening are actually special cases of a process known as color filtering. A color filter is any RGB triple applied to an entire image. The filtering algorithm adjusts each pixel by the amounts specified in the triple. For example, you can increase the amount of red in an image by applying a color filter with a positive red value and green and blue values of 0. The filter (20, 0, 0) would make an image’s overall color slightly redder. Alternatively, you can reduce the amount of red by applying a color filter…arrow_forwardWrite and implement a program using JAVA and GUI, to find the summation and multiplication for three variables A (JTextField), B (JTextField) and C (JTextField), use button or checkbox to find the results which displayed in a label.arrow_forward
- use Pyhton. The tossball simulation we developed together in class is attached to this week's notes. Study it carefully to understand exactly what it is doing. It currently launches a ball in the main graphics window. You need to make the following changes and improvements and send me at the end your finished project in zipped folder format. Only python modules should be included. 1) Add a new class named "Cannon". This class it to represent the cannon that launches the balls. It should draw a rectangle (hint: use Polygon class from Graphics.py) at the launch point. Its width should be equal to the diameter of the balls that it shoots out and its length should be proportional to the speed, say something like speed * 0.15. The cannon should also be directed in the same direction that the balls shooting. Add proper width, height, and angle attributes to the class for supporting the settings above. The balls should start from the bottom of the cannon and be projected out through the…arrow_forwardNew JAVA code can only be added between lines 9 and 10, as seen in image.arrow_forwardSolve it with java please and post a screenshotarrow_forward
