Barbell lifting for multi-layer wavelet coding
A method for coding video data includes scalably generating layers of wavelet coefficients based on a frame of video data, scalably generating motion vector data associated with the plurality of layers, and combining the motion vector data and the plurality of layers of wavelet coefficients into a coded video frame representing the frame of video data. The method may further include transmitting the coded video frame. A system for coding video data includes a temporal decomposition module scalably applying a barbell function to a frame of video data, and a motion vector module scalably coding motion vector data at multiple levels of refinement.
