Adaptive Color-Space Transform in HEVC Screen Content Coding.
IEEE Journal on Emerging and Selected Topics in Circuits and Systems(2016)
摘要
The screen content coding (SCC) Extensions of high efficiency video coding (HEVC) employs in-loop adaptive color-space transform (ACT) technique to explore the inter-color-component redundancy, i.e., statistical redundancy among different color components. In ACT, the prediction residual signal is adaptively converted into a different color space, i.e., YCgCo. The rate-distortion criteria is emplo...
