In the research field of compression, the usual goal is to achieve the best possible compression rate. The best known algorithms, however, are very slow, and sometimes impractical for real-world applications. When dealing with images, the situation becomes especially worse considering the fact that photo resolutions are ever increasing. Image sizes of 4500×3000 pixels (or more) are not uncommon. U
