Objective model for perceptual sharpness in image sequences

摘要

Currently, the analog video world is in transition to digital video. Along with that transition is the need for analysis techniques that can be applied to digital image sequences. In particular, objective techniques that can analyze the digital image sequences in a way that reflects human perception is being pursued. These objective measures can be valuable in many areas including quality assessment. Currently, subjective assessment of video is time consuming and expensive. Therefore, an objective assessment that accurately reflects the human visual system cna be valuable. This apper examines the perceived quality of shifting and blurred sequences. It introduces an objective quality measure for assessing the sharpness in digital image sequences. The model is compared to two other objective measures and a subjective assessment.
