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.

Abstract translation: 用于客观地确定感知的视频/图像质量的技术，所述技术包括接收包括经编码的视频/图像数据的退化位流，并且随后解析比特流以提取一个或多个视频/图像编码组件。 视频编码组件可以包括帧内预测模式，离散余弦变换（DCT）系数，运动信息或其组合，并且可以用作客观地预测体验质量（QoE）或运动视点得分（MOS） 劣化比特流的得分。

Abstract: A system that incorporates teachings of the exemplary embodiments may include, for example, means for generating a disparity map based on a depth map, means for determining accuracy of pixels in the depth map where the determining means identifies the pixels as either accurate or inaccurate based on a confidence map and the disparity map, and means for providing an adjusted depth map where the providing means adjusts inaccurate pixels of the depth map using a cost function associated with the inaccurate pixels. Other embodiments are disclosed.
