Abstract

The invention is a new effective and fast method and apparatus for still image compression, transmission and decompression. The present invention implements optional sorting and encoding methodologies to create object-oriented, shape coding or region coding in still image and video coding that is content accessible, scalable and computationally efficient. The invented, multiplexed transmission regime ensures a robust, scalable and content accessible bit stream and includes a dynamic, bit budget control architecture.
