H. 263+ Region-of-Interest Video Coding with Efficient Skin-Color Extraction
Ming-Chieh Chi, Jyong-An Jhu, Mei‐Juan Chen · 2006
This study designs a novel skin-color extraction method to automatically select the ROI regions for videophone and videoconferencing applications. We propose a linear QP prediction at the macroblock layer to control the qualities at different regions for region-based H.263+ video codec with the option mode of modified quantization.
