A method for the objective video quality assessment is proposed.By using the Human Vision System (HVS) properties into the intra and inter frame processing,the proposed method can overcome the traditional Peak Signal-to-noise Ratio (PSNR) in the application of video quality evaluation.Based on the principle that human's eyes tend to be more sensible to the degradation happening in the edge of image,a detection scheme is designed to evaluate the distortion in the intra frame.By measuring the temporal energy,know the typical features in the temporal domain and then use them to modify the evaluation result of the spatial domain.The proposed method inherits the advantages of the traditional PSNR such as simpleness and convenience and has better correlation with the subjective perception.And it can be easily implemented and integrated in the equipment system of detection.
