A reduced reference video quality assessment of H.264 and mpeg2 codec based on sharpness metric
Résumé
In this paper, we propose a new perceptually significant video quality metric for the H.264/Motion Picture Expert Group (MPEG)-4 Advanced Video Coding (AVC) and MPEG2 standard. Ourmethod operates in the spatial domain by using the Sobel filter. The proposed approach does notrequire a high computational complexity and can be suitable for real-time evaluation. We evaluatethe performance of the proposed method by using three Common Intermediate Format sequences at dif-ferent compression rates. The comparison of the obtained results is made with some video qualitymodels using “LIVE”, “IVP” and “IRCCyN/IVC 1080i” databases. The performance metrics, i.e. Pearson and Spearman correlation coefficients, indicate that the proposed method gives a good performance inH264 and MPEG2 codec distortions with the three databases comparing with other models.
