Hybrid JPEG/recursive block coding of images

The tile effect is an artifact which considerably degrades the visual quality of the images coded at bit rates less than 1 bpp. A new algorithm called JPEG/RBC which is based on a two source decomposition of a noncausal model fits closely within the broad framework of the JPEG standard. Preliminary results indicate substantial improvement in performance and bit rates in addition to the mitigation of the tile effect.
