Recently, video quality evaluation method based on structure similarity (SSIM) has been widespread concerned. Compares with other traditional methods, it has a better performance and is simple to calculate. In this paper, we follow a new simple calculate metrics method in quaternion model, by introducing structure similarity as three parts of the quaternion, and the inter-frame-different (IFD) as the forth part to metric the structural distortion between the two frames, then we extract feature vector by using quaternion singular value decomposition. The algorithm is tested on the video quality experts group (VQEG) Phase I FR-TV test data set.
