Three-dimensional shape-adaptive discrete wavelet transforms for efficient object-based video coding
13 years 6 months ago
In this paper, we present an object-based coding scheme using three-dimensional shape-adaptive discrete wavelet transforms (SA-DWT). Rather than straightforward extension of 2D SA...
