Semi-Regular Geometric Kernel Encoding & Reconstruction for Video Compression

ICASSP 2020accepted

Conventional video coding schemes employ a hybrid motion prediction / residual transform coding paradigm, which only exploits redundancy in individual pairs of video frames for compression gain. However, rigid geometric structures in 3D space—e.g., a building in a scene’s background—persist across t…

Complexity Reduction Algorithm for Optimum Quantizer Design Based on Amplitude Sparseness

ICASSP 2018accepted

The design of an optimum quantizer can be formulated as an optimization problem that finds the quantization indices that minimize the quantization error. One solution of the optimization problem is DP quantization, an approach based on dynamic programming. It is known that a quantized signal does no…
