Abstract:
A method encodes a video by applying a dual-tree discrete wavelet transform to the video to generate sequences of wavelet coefficients. The sequences are compressed to produce a compressed bitstream corresponding to the video. The compression iteratively selects the wavelet coefficients in a large to small order, and entropy encodes the selected wavelet coefficient.
