the attached utility is a work I ve submitted to the university It shows what a jpeg compression is all about. the function implements the DCT TRANSforM, using a matrix operator. note that matlab has a function for the DCT and iDCT TRANSforMs that might be more efficient.

Image Compression A collection of simple routines for image compression using different techniques. 图象压缩的不同方法 BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine TRANSforM. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.

The tca package is a Matlab program that implements the tree-dependent component analysis (TCA) algorithms that extends the independent component analysis (ICA), where instead of looking for a linear TRANSforM that makes the data components independent, we are looking for components that can be best fitted in a tree structured graphical model. The TCA model can be applied in any situation where the data can be assumed to have been TRANSforMed by an unknown linear TRANSforMation.

These three articles involves the combination of wavelet and MCTF. MCTF means motion-compensated-time-filter. It makes wavelet TRANSforM more popular because of the high compression efficiency.
