This toolbox provides functions for different types of transformation in image
processing algorithms. The functions are dct2 and their inverses, radon, walsh,
hadamard transformations etc.
Functions available in this toolbox are:
1. dct2, idct2
2. walsh transform
3. hadamard transform
4. radon transform
5. some special matrix generation functions used for image processing
Help files are also included in this toolbox.
