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.

What is the block size for the division for the image in Slantlet Transform?
What is it used for ?

For the slant transform, it is three scales iterated?

nice work

John Kramer

good work

Every transform coding is done efficiently..just the way it should have been done...A class analysis
