Video Coding Using 3D Dual-Tree Wavelet Transform
EURASIP Journal on Image and Video Processing, 2007 This work investigates the use of the 3D dual-tree discrete wavelet transform (DDWT) for video coding. The 3D DDWT is an attractive video representation because it isolates image patterns with different spatial orientations and motion directions and ...
