Image Compression and Enhancement:

Q$4.$ you are given a $44$ image with $2$ bits per pixel $($fig$-1).$

Marks: $)=(20$

a$.$ Calculate its entropy and comment whether Huffman coding can be used for compression of this image.

Also calculate compression ratio and average number of bits$/$pixel for this image

b$.$ Can this image be enhanced using histogram equalization? Comment and draw the enhanced image

c$.$ Repeat complete part a for image with same specifications but different intensities given in fig$-2$

$\backslash$table$[[1,1,2,2],[3,3,0,0],[2,1,1,2],[3,0,3,0]]$

$\backslash$table$[[1,3,1,1],[1,1,1,3],[2,2,2,0],[0,2,3,2]]$
