Summary:A no-reference blockiness metric which is used to measure blocking artifacts of H.264/AVC coding videoconference, is presented in this paper. The encode information extracted from bit stream in the decoding process and the human face information are used to construct a region-of-interest (ROI) map. Based on the ROI map, the Sobel operator is adopted to make the fast estimation of blocking artifacts for H.264 videos. Experimental results show that the proposed method can measure blocking artifacts consistent with the real quality and show high sensitivity to the bit rate.
