Compression is very important for multimedia applications, because it reduces the amount of space for depositing the information, and the bandwidth required for sending it through a computer network. Multiresolution analysis performs a wavelet decomposition that decorrelates the signal data, in preparation for the quantization step and the final redundancy reduction. This article presents a simple algorithm for performing the decomposition of images and propounds a quantization method that takes into account the human eye contrast sensitivity function.
