ERROR-RESILIENT CODER OF IMAGE SEQUENCES AND VIDEO

摘要

A method, computer system, and a computer program product is disclosed for encoding a sequence of frames as one or more compressed bitstreams, the method includes a processor obtaining a sequence of frames in an order and performing a wavelet transform on each frame of the sequence of frames independently in the order. The processor constructs a significant points list and an insignificant sets list, creating one or more spatial trees comprised of branch nodes of the list of insignificant sets for each frame of the sequence of frames. The processor initializes the significant points list and the list of insignificant sets for each frame and identifies a most significant bit in each frame and for each frame, selects at least one coding unit and creates a progressive significance map for coding. The processor writes a global header and a local header for the compressed bitstreams for each coding unit.
