摘要： A system to process a signal sequence is described. A hybrid block matching and transform based N-Dimensional signal sequence encoder and decoder is disclosed. The encoder includes encoder side block matching predictor, which includes entropy based cost function which can be estimated from certain energy measure of the block matching difference; a fast block matching search method to learn the results from neighboring blocks and to perform large range search with only a small number of points to visit.

摘要： A system and method to process a signal sequence is described. A hybrid block matching and transform based N-Dimensional signal sequence encoder and decoder is disclosed. The encoder includes encoder side block matching predictor, which includes entropy based cost function which can be estimated from certain energy measure of the block matching difference; a fast block matching search method to learn the results from neighboring blocks and to perform large range search with only a small number of points to visit. A method is disclosed to dynamically adjust the cost function parameters and other coding control parameters based on encoder outputs, and to optimize the quality and performance of the encoder. A method is disclosed to enable exploring and rapid processing of fractional grid points for n-dimensional block matching. A hybrid block matching and transform based n-dimensional signal sequence decoder is disclosed. A memory organization and processing array structure to enable efficient processing of n-dimensional signal frames includes an n-dimensional memory capable of rapidly storing and accessing blocks of n-dimensional signals; a multi-level mass memory structure to store massive amount of data before transferring to the n-dimensional memory; and a signal processor array to process the data in the n-dimensional memory.
