A hybrid image compression scheme using block-based fractal coding and DCT

Fractal image compression is a recent technique among lossy image coding methods that provides several improvements over existing Fourier series compression schemes. In this work we propose and investigate a class of hybrid image coders based on fractal coding and DCT based algorithms. These hybrid algorithms outperform pure fractal coders and show better behavior as compared to both pure fractal and DCT-based coders.
