For backward compatible high dynamic range (HDR) video compression, the HDR sequence is reconstructed by inverse tone-mapping a compressed low dynamic range (LDR) version of the original HDR content. In this paper, we show that the appropriate choice of a tone-mapping operator (TMO) can significantly improve the reconstructed HDR quality. We develop a statistical model that approximates the distortion...
Scalability in video coding is becoming the primary choice for providing quality of service (QoS) guarantees in wireless video communication. In this paper, we develop real-time rate and distortion prediction models for medium grained scalable (MGS) coded video streams. These models allow mobile video encoders to predict the packet size and corresponding distortion of a video frame using only the...
