    摘要: Spatial distortion (i.e., when a frame is viewed independently of other frames in a video sequence) may be quite different from temporal distortion (i.e., when frames are viewed continuously). To estimate temporal distortion, a sliding window approach is used. Specifically, multiple sliding windows around a current frame are considered. Within each sliding window, a large distortion density is calculated and a sliding window with the highest large distortion density is selected. A distance between the current frame and the closest frame with large distortion in the selected window is calculated. Subsequently, the temporal distortion is estimated as a function of the highest large distortion ratio, the spatial distortion for the current frame, and the distance. In another embodiment, a median of spatial distortion values is calculated for each sliding window and the maximum of median spatial distortion values is used to estimate the temporal distortion.

    摘要: A particular implementation forms an initial reconstructed image block from inverse quantization and inverse transform, and further refines the reconstructed image block using pixels from neighboring reconstructed blocks. The image block may be refined using a bilateral filter, whose space parameter and range parameter are adaptive to the quantization parameter. The particular implementation can be used in both encoding and decoding when reconstructing an image block. When used in encoding, the particular implementation can be used jointly with coefficient truncation, where some non-zero transform coefficients are set to zero. The number of remaining non-zero transform coefficients after coefficient truncation may be adaptive to the quantization parameter, the variance of the image block, the number of non-zero transform coefficients of the image block, and the index of the last non-zero transform coefficient in a zigzag scanning order.
