Fast Hybrid Fractal - VQ Color Compression in Wavelet Domain

Fractal image compression is a technique based on the representation of an image by a contractive transform and iterated function system. Resultant attractor of contractive transform is close to the original image. Though pure fractal compression cannot give compression ratio comparable to the state of the art schemes, hybrid schemes incorporating fractal compression and alternative techniques have achieved good compression ratio. This paper presents novel color image compression algorithm using fractal compression and vector quantization, which utilizes correlation between RGB components.
