The following assignment required me to implement 4 Types of Image Smoothing Filters.

For this TIME I need HELP with implementing Gaussian filter and Median filter ONLY!

You may use Source code from online resources. Make sure to CHECK OUT THE SKELETON PROGRAM PROVIDED(2 java files) and You must implement this filter in SmoothingFilter.java file.

Your Task: The four image smoothing filters you need to implement are 5x5 mean filter, 5x5 Gaussian filt with user-specified parameter, 5x5 median filter, and 5x5 Kuwahara filter. Making use of the mo efficient implementation based on the property of the filters is required. Be careful when handli pixels near the boundaries of the image. If a pixel is outside of the image, the closest pixel that is l Smoothing Filter Add noise 55 mean Sigma 55 Gaussian 5x5 median 55 Kuwahara the image should be used. Output of the skeletal program Getting Started: A skeletal program is supplied to get you started, which you are required to use as the basis of yo implementation. To run the skeletal program, you need to put the testing images in the same folde The program opens a window that contains two panels and displays the test image in both panels. a demo, the program adds noise to the input image when the first button is pressed. Smoothing Fitte ye Add noise 55 mean 55 Gaussian 5x5 medan 55 Kuwahara Output of a sample solution Grading Your program will be tested and graded using a standard Java environment. The grade willb based on your program's functionality (whether or not it works under different settings), as well as th efficiency of your implementation. The weights for different components are as follows Result of 5x5 mean filtering 20% Result of 5x5 Gaussian filtering 20% Result of 5x5 median filtering 30% Result of 5x5 Kuwahara filtering 30% * *
