Paper Abstract

Thresholding is a technique for suppressing small transform coefficients in DCT-based coding. Recently, dynamic programming has been presented to optimize thresholding in a rate-distortion sense. This contribution investigates the extension of this method for SNR scalability. Because of the tight coupling between base and enhancement layer in SNR scalability, a 2D dynamic programming algorithm has been developed.
