Salient object detection can provide the attention information of viewers and has the potential to be employed in many real-time interactive and display systems. In this paper, based on an existing top-down salient object detection algorithm, a real-time salient object detection engine is proposed and implemented. With several memory bandwidth optimization techniques and hardware optimization techniques,...
In this work, a perceptual quality-regulable H.264 video encoder system has been developed. Exploiting the relationship between the reconstructed macro block and its best predicted macro block from mode decision, a novel quantization parameter prediction method is built and used to regulate the video quality according to a target perceptual quality. An automatic quality refinement scheme is also developed...
