Simulation of DCT, Walsh, Hadamard, Haar and Slant transform using variable block sizes

Performs non sinusoidal image transforms on gray-scale images and DCT using the dct matrix.

Performs non sinusoidal image transforms on gray-scale images and DCT using the dct matrix of given order of block size.
The reconstructed image is exactly identical to the original image depicting that the transforms are lossless. Also, codes for generation of walsh, slant and haar matrices have been included for the transform.
