Low Bit-Rate Video Coding with 3D Lower Trees (3D-LTW)
The 3D-DWT is a mathematical tool of increasing importance in those applications that require an efficient processing of volumetric info. However, the huge memory requirement of the algorithms that compute it is one of the main drawbacks in practical implementations. In this paper, we introduce a fast frame-based 3D-DWT video encoder with low memory usage, based on lower-trees. In this scheme, there is no need to divide the input video sequence into group of pictures (GOP), and it can be applied in a continuous manner, so that no boundary effects between GOPs appear.
