This package contains some MatLab tools for multi-scale image processing. Briefly, the tools include: - Recursive multi-scale image decompositions (pyramids), including Laplacian pyramids, QMFs, Wavelets, and steerable pyramids. These oper

Implementation of JPEG compression algorithm with JFIF header being appended.This project involves writting code for following steps : Chroma subsampling,partitioning ,level shifting,DCT,quantization,zigzag scanning(involves DC differential coding &

They are the programs of uniform quantization and non-uniform quantization. In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by
