Compute the Radon transform of an image, I , for a specific set of angles, theta , using the radon function. The function returns, R , in which the columns contain the Radon transform for each
Compress an image using the Discrete Cosine Transform (DCT). The example computes the two-dimensional DCT of 8-by-8 blocks in an input image, discards (sets to zero) all but 10 of the 64 DCT
