In-Scale Motion Compensation for Spatially Scalable Video Coding
In existing pyramid-based spatially scalable coding schemes, such as H.264/MPEG-4 SVC (scalable video coding), video frame at a certain high-resolution layer is mainly predicted ei...

RD-Optimization of Hierarchical Structured Adaptive Vector Quantization for Video Coding
This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...

An Iterative Detection Aided Irregular Convolutional Coded Wavelet Videophone Scheme Using Reversible Variable-Length Codes and
— In this paper, we characterize the achievable performance of a wavelet encoding-based videophone system, which further compresses and protects the wavelet-based video codec’s...

Fine spatial scalability in wavelet based image coding
Wavelet transform based image coding algorithms have the two inherent scalable features of SNR scalability and spatial (or resolution) scalability. However, fine scalability is sup...
