CCSDS_LDPC

The discrete cosine transform (DCT) is a technique for converting a signal into elementary frequency components. It is widely used in image compression. Here we develop some simple functions to compute the DCT and to compress images. These functions illustrate the power of Mathematica in the prototyping of image processing algorithms. The

OMP orth mat persuit bys ome good coder this is good implementation

it is a matlab guide , can be useful for mini projects and final projects.It provedto be very much useful for me ,hope u guys will make use out of it .
