Adaptive Clipping in JEM
Research Paper / DCC-2017 / Apr 2017 / Image Processing, Video Coding

This paper presents an adaptive clipping technique with optimized syntax in the video coding Joint Exploratory Model (JEM), which exploits the signal characteristics of the video sequence. The component-wise clipping bounds are coded for each slice. Two encoding methods leveraging the efficiency of the proposed technique are then described. The first one consists in modeling the errors induced by the clipping process in the Rate Distortion Optimization. The second one aims at reducing the cost of transform coefficients by smoothing the residuals. Finally, experimental results are provided and several variants are discussed.
