DCT projects and source code

Dct Matlab Code

A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations.

Simulation of dct, walsh, hadamard, haar and slant transform using variable block sizes in matlab

The following Matlab project contains the source code and Matlab examples used for 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 of given order of block size.
