Abstract:
Techniques for objectively determining perceived video/image quality, the techniques including receiving a degraded bit-stream comprising encoded video/image data, and subsequently parsing the bit-stream to extract one or more video/image coding components. The video coding components may include intra-prediction modes, discrete cosine transform (DCT) coefficients, motion information, or combinations thereof, and may be used as a basis for objectively predicting a Quality of Experience (QoE) or Motion Opinion Score (MOS) score of the degraded bit-stream.
