The benefits of utilizing the spatial-frequency sensitivity of the human visual system in video coding have been known for decades and are incorporated into video standards, such as MPEG2, MPEG4, and H.264/AVC, as well as into still image-coding standards, such as JPEG and JPEG-2000. However, all of these standards utilize frequency weighting that is adaptive only at the picture level. In contrast...
In the perceptual video coding scheme, the properties of the human visual system (HVS) are usually used to improve the subjective quality. The frequency sensitivity is one of the most important properties of HVS and related techniques have been adopted in many video coding standards, such as MPEG2 and H.264/AVC High Profile. However, the frequency weighting algorithms used in those standards are all...
