Hybrid fractal image coding with quadtree-based progressive structure
A progressive structure is proposed for fractal image coding. The quadtree depth information is utilized in the progressive structure. A hybrid fractal image coding using traditional and no-search methods is suggested. A better progressive performance is reached compared with the traditional approach. A threshold is employed to balance the image quality and encoding efficiency.
