Use SVD method to compress and decompress images in the MATLAB.
Compression function. The input is an image file and k. The output is a text file containing the reduced U, V , and the reduced diagonals of ?.
Decompression function. The input is the output of the compression code. The output is an image (you can use imshow for this purpose).
