Abstract
A method and system for coding a multi-view video having multiple views based on temporal decomposition and view decomposition is provided. A multi-view video coding (“MVC”) system provides a disparity compensated view filter based on a generic lifting transform that is used in conjunction with a motion compensated temporal filtering and a two-dimensional spatial discrete wavelet transform to decompose a multi-view video into four-dimensional wavelet coefficients. The MVC system performs a hierarchy of decompositions for each view that may be a combination of temporal decompositions and view decompositions.
