Genetic Algorithm based Fractal Image Compression
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 2
Abstract
Abstract:Fractal Image Compression is a lossy compression technique that has been developed in the early 1990s. Fractal image compression explores the self-similarity property of a natural image and utilizes the partitioned iterated function system (PIFS) to encode it. The fractal image compression problem had three major requirements: speeding up the compression algorithm, improving image quality and increasing compression ratio. So far, several methods have been proposed in order to speed-up fractal image compression. The time is essentially spent on the search of the similar domain block. This paper aims to present a method that uses Genetic algorithms to speed up computation time in fractal image compression with acceptable image quality and high compression rate. These improvements are obtained by encoding all regions in the image with different size blocks.
