Visual Distortion Assessment With Emphasis on Spatially Transitional Regions
2004
IEEE transactions on circuits and systems for video technology (Print)
It is known that the human visual system (HVS) does not pay equal attention to each error and even region in judging picture quality. In this paper, we combine a perceptual model with an integrated detection of the spatially transitional regions in visual distortion evaluation to better match the HVS perception to visual quality. For decompressed images or video, the spatially transitional regions are the regions where major perceptually disturbing artefacts caused by edge impairments (mainly
