DCT approximation for low bit rate coding using a conditional transform
A transform approximation is explored for speeding up the software compression of images and video. It is used to replace the regular DCT whenever only few DCT coefficients are ac...

Fractal Image Compression on a Pseudo Spiral Architecture
Fractal image compression is a relatively recent image compression method which exploits similarities in different parts of the image. The basic idea is to represent an image by f...

Improved Antidictionary Based Compression
The compression of binary texts using antidictionaries is a novel technique based on the fact that some substrings (called “antifactors”) never appear in the text. Let × be a...

Reducing code size with echo instructions
In an embedded system, the cost of storing a program onchip can be as high as the cost of a microprocessor. Compressing an application’s code to reduce the amount of memory requ...
