This is a Matlab implementation for the forwards additive version of ECC image alignment algorithm based on the paper "G.D. Evangelidis, E.Z. Psarakis, Parametric Image Alignment using Enhanced Correlation Coefficient Maximization", IEEE Trans. on PAMI, vol. 30, no. 10, 2008. ECC algorithm is a... Platforms: Matlab

The image compression routine uses the concept of factorizing the image-matrix & using only the required 'key' values that represent the original image-matrix.There is loss of data, in the sense that, the original matrix cannot be regenerated from the compressed image-data.Currently, this routine... Platforms: Matlab

This is a simple implementation of the famous LZW algorithm. Platforms: Matlab

Improved Gray Scale (IGS) codes are used for the elimination of false contouring in images, and image compression. This Python program generates the IGS codes for a set of input gray level values. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script demonstrates the influence of range reduction algorithm at low bitrate encoding using JPEG encode. The range [0-255] of pixel values is mapped to [64-235] in this script using a look-up-table. Subsequently, the file is compressed to achieve the same bit-rate (file size) as that of the... Platforms: Matlab

LZ77 is a compression algorithm upon which most popular compression formats are based; PKZIP, GZIP, LHA, RAR, etc. This script allows you to compress blocks having the size of maximum 256 bytes. Platforms: Windows, Mac, *nix, Python, BSD Solaris

The k-means algorithm is widely used in a number applications like speech processing and image compression.This script implements the algorithm in a simple but general way. It performs four basic steps.1. Define k arbitrary prototypes from the data samples.2. Assign each sample to the nearest... Platforms: Matlab
