Improvement of Adaptive Fractal Image Coding Algorithm for GPGPU Systems using Index Vectors

摘要

Fractal image coding is one of the most prominent compression technologies. It can be also used for industrial applications like image retrieval methods and image indexing methods [1]. In addition, the adaptive approach can achieve the image compression with given quality level by changing the size of range blocks in any location, so the adaptive approach can achieve a high compression rate with less data than the non-adaptive method, but the naive parallel implementation may result in a bad performance due to the imbalance of work loads.
