The framework achieves real-time execution while outperforming state-of-art full-reference and no-reference video quality assessment methods. The performance of the proposed method is verified by correlation measurements with the aforementioned objective and subjective scores. Proof-of-concept experiments are conducted via comparison with: 1) video sequences rated by a full-reference quality metric, and 2) H.264-encoded sequences from the LIVE video dataset which are subjectively evaluated through differential mean opinion scores (DMOS). The hand-crafted features and network dynamics are designed in a manner to ensure a high correlation with human judgment of quality as well as minimizing the computational complexities. Temporal and spatial features are extracted from the encoded bit-stream and pixel values to train and validate a fully connected neural network. ![]() A real-time no-reference video quality assessment (VQA) method is proposed for videos encoded by H.264/AVC codec. One primary challenge in developing no-reference (NR) video quality metrics is achieving real-timeliness while retaining the accuracy. The ever-growing video streaming services require accurate quality assessment with often no reference to the original media. ![]()
