In this paper, we present an adaptive intra-frame rate-quantization (R-Q) model for H.264/AVC. The R-Q model, which is a generic relationship among the quantization value, data bits and the frame complexity, provides a mechanism to properly select the quantization value for an intra frame at a given target bit rate. Based on the proposed intra-frame R-Q model, a bit allocation scheme for intra frame...
In the scalable video coding (SVC) standard, interlayer intra prediction (ILIP) is one of the most fundamental coding tools used to reduce bit rate. The prediction block of macroblock (MB) in enhancement layer (EL) is obtained by upsampling the co-located base layer (BL) block. In this paper, we propose a new ILIP method by introducing the adaptive signal processing techniques. Adaptive Wiener filters,...
