M. Breazu. Rate-distorsion optimized quadtree partitioning method. In Proc. of the Conference Fractals in Engineering, Pages 36-42, Delft, June 1999.
The paper introduces a new method based on rate-distortion optimised quadtree partitioning to fractal image compression. the method starts with a complete quadtree splitting phase where the best corresponding domain for each range is searched and kept. Then, the corresponding tree is pruned according to a rate-distortion criterion. Experimental results prove that our method yields a better rate-distortion curve than the classic quadtree partitioning scheme. the classical (empirically chosen) tolerance flag is no longer needed and the stop condition is replaced by a more useful desired bit-rate (compression ratio) criterion.
