Abstract: In this paper, a new embedded 3D wavelet video coding method with 3D SPECK is considered. The method is based on real 3D wavelet packet transform, and implements a three dimensional extension of SPECK in still image coding by defining a new block structure. The method does not involve motion estimation, and has lower computational complexity and coding latency , and can make full embedded video streams. Experimental results show that the method is able to compress video rapidly and effectively, and is a video coding method with great potentials.
