(English Abstract)
Objective video-quality assessment method is one of essential components to indicate better user-quality. This work proposes a video-quality metric with no-reference method for encoded H.264/AVC that offers less complexity and higher accuracy and that is well-matched with subjective video quality. The proposed quality metric uses the bitstream information such as quantization parameters, motion vectors, locations and patterns of packet loss, and the Group of Picture (GOP) size. The proposed one includes two parts: the encoding distortion and the transmission distortion. The encoding distortion is from lossy encoding and the transmission distortion from the error propagation properties with packet loss. The performance of the proposed metric outperforms the existing schemes in terms of the correlation with subjective Differential Mean-Opinion-Score (DMOS) which reflects the human perception quality.
