4) Take the cameraman image (standard test image of MATLAB). a) Determine the sample entropy of this image b) Get a Huffman coder (from internet). Apply to cameraman image, and determine the compression ratio. c) Now, apply the ZIP operation, find the compression ratio. d) Finally, Find the JPEG-LS (LOCO) coder from the internet. This is a lossless coder tuned for images. Apply it to the cameraman image, determine the compression ratio. Comment on your observations. Why are the first three methods inefficient? e) 4) Take the cameraman image (standard test image of MATLAB). a) Determine the sample entropy of this image b) Get a Huffman coder (from internet).
