Optical-Flow Based Nonlinear Weighted Prediction for SDR and Backward Compatible HDR Video Coding Open
Tone Mapping Operators (TMO) designed for videos can be classified into two categories. In a first approach, TMOs are temporal filtered to reduce temporal artifacts and provide a Standard Dynamic Range (SDR) content with improved temporal …
Optimal Adaptive Quantization Based on Temporal Distortion Propagation Model for HEVC Open
Optimal adaptive quantization is one of the key points to optimize the coding efficiency of video encoders. The latest block-based video compression standards, such as high-efficiency video coding (HEVC), extensively use predictive coding …

Gradient-Based Tone Mapping for Rate-Distortion Optimized Backward-Compatible High Dynamic Range Compression Open
This paper addresses the problem of designing a global tone mapping operator for rate distortion optimized backward compatible compression of high dynamic range (HDR) images. We address the problem of tone mapping design for two different …
