This paper investigates the effect that the QP offset value has on the coding performance of HEVC. We relate QP offset to the type of texture content present in the sequence. These then are used to develop a low-complexity adaptive QP offset selection method. This enables in-loop configuration of the QP offset parameter in a way that is content dependent and utilizes available encoding statistics...
Previous work has shown that spatial resampling can improve rate-distortion performance by providing a higher and more consistent level of video quality at low bitrates. Rate control aims to regulate the video bitrate in accordance to the bit budget. While this is a well studied problem in the single resolution case, very little progress has been made on the adaptive resolution case. In this paper...
This work presents two studies on the topic of coding highly textured content with H.265/HEVC. The aim of the studies is to identify any potential for improvement in the performance of the codec with this type of content. Both studies employ a texture-focused video database developed by the authors. Study I evaluates the performance of H.265/HEVC relative to H.264/AVC for the case of static, dynamic...
