Video Quality Assessment Based on Quatemion Singular Value Decomposition
摘要
Abstract
Accurate objective quality metric is crucial for various video processing applications. Although the area of image quality assessment has attained maturity in recent years, video quality assessment still has a long way to go before it reaches the levels of success achieved by still image quality metrics. In the paper, we present a new approach to video quality assessment based quatemion singular value decomposition(QSVD),which take the luminance,chrominance ,edge energy and motion energy of each pixel as the four parts of a quatemion, and the entropy as the degree of visual interest of regions to weight each block. We demonstrate the performance of our algorithm by testing it on the Video Quality Expert Group(VQEG)Phase Ⅰ FR-TV dataset,the results show that our method is competitive with state of the art quality assessment methods and has good correlation with perceived video quality.关键词
