Question: Write a Matlab function that takes as an input an image block of size 16X16 size and type uint8, and computes (1) the 2D discrete

Write a "Matlab function" that takes as an input an image block of size 16X16 size and type uint8, and computes (1) the 2D discrete cosine transform for the block and stores the output in a variable called DMATRIX, (2) then from DMATRIX computes the inverse 2D discrete cosine transform and stores the output in a variable called IDMATRIX. ** The function must have two return variables which are DMATRIX and IDMATRIX.
