APPARATUS AND METHOD FOR OBJECTIVE ASSESSMENT OF DCT-CODED VIDEO QUALITY WITH OR WITHOUT AN ORIGINAL VIDEO SEQUENCE |
摘要 |
<p>A new approach to objective quality assessment of DCT-coded video sequences, with or without a reference is proposed. The system is comprised of a proprietary segmentation algorithm, a feature extraction process and a nonlinear feed-forward-type neural network for feature analysis. The methods mimic function of the human visual system (HVS): A neural network training algorithm is used for determining the optimal network weights and biases for both system modes of operation. The proposed method allows for assessment of DCT-coded video sequences without the original source being available (pseudo-reference mode). The pseudo-reference mode is also comprised of a proprietary DCT-coded video (MPEG) noise reducer (MNR), co-pending patent application no. 60/592,143.</p> |
