Write a matlab code for following :

Load image Balloon.tif into Matlab. Develop a function to mark all pixels in green with 1 and 0 for the rest. Display the result image Convert it into a grayscale image, denoted with img1 Create a copy of the clean grayscale image, denoted with img2, in the memory and add salt and pepper noise to it using imnoise Remove salt and pepper noise using function medfilt2 and display the clean (img1) and denoised image side by side (using subplot function) Create a copy of the clean grayscale image, denoted with img3, in the memory and add Gaussian noise using imnoise. Remove Gaussian noise using imgaussfilt Enhance the denoised img3 to recover the fine edges
