摘要： There are provided methods and apparatus for multi-view video coding. A video encoder includes an encoder for encoding a block in a picture by choosing between temporal prediction and cross-view prediction to enable a prediction for the block. The picture is one of a set of pictures corresponding to multi-view video content and having different view points with respect to a same or similar scene. The picture represents one of the different view points. A high-level syntax is used to indicate the use of cross-view prediction for the block.

摘要： A decoder (10) conceals errors in a coded image comprised of a stream of macroblocks by examining each macroblock for pixel errors. If such errors exist, then each of at least two macroblocks pictures from each of two different pictures are weighted to yield a weighted prediction (WP) for estimating missing/corrupt values to conceal the macroblock found to have pixel errors.
摘要翻译： 解码器（10）通过检查每个宏块的像素误差来隐藏由宏块流组成的编码图像中的错误。 如果存在这样的错误，则对两个不同图像中的每一个的至少两个宏块图像中的每一个进行加权，以产生用于估计丢失/损坏值的加权预测（WP），以隐藏发现具有像素误差的宏块。

摘要： Film grain simulation within a receiver 4 occurs by first obtaining at least one block of pre-computed transformed coefficients. The block of pre-computed transformed coefficients undergoes filtering responsive to a frequency range that characterizes a desired pattern of the film grain. In practice, the frequency range lies within a set of cut frequencies fHL, fVL, fHH and fVH of a filter in two dimensions that characterizes a desired film grain pattern. Thereafter, the filtered set of coefficients undergoes an inverse transform to yield the film grain pattern.

摘要： Temporal concealment of missing/lost macro blocks relies on the direction mode derivation process typically standardized in video decoders. Upon detecting an error in the form of a picture (FIG. 1) a co-located macro block is found previously transmitted picture. The motion vector for that co-local macro block is determined (FIG. 2). The identified macro block is predicted by motion compensating data from a second previously transmitted picture in accordance with the motion vector determined for the co-located macro block (FIG. 3).

摘要： A decoding arrangement for decoding pictures in an incoming video stream includes a noise generator for adding a dither signal containing random noise to the pictures after video decoding, to improve the subjective video quality. The noise generator adds noise to each pixel in an amount correlated to additive noise of pixels in a prior picture, either a previously displayed picture (i.e., a previously decoded picture to which noise has been added), or a previously decoded picture.

摘要： Reduction in the blockiness of a simulated film grain block can be achieved either by the use of adaptive downscaling or adaptive deblocking filtering to adjust the intensity of the pixels at the block edge in accordance with at least one film grain block parameter, such as film grain size, intensity and texture. Performing such adaptive downscaling or adaptive deblocking filtering achieves improved performance at lower computational cost by avoiding modification of film grain block pixels in lesser affected areas.

摘要： Concealment of errors in a coded image occurs by first selecting an inter-prediction mode in accordance with the coding of the image. The selected intra-prediction mode, while ordinarily used to specify the direction for obtaining a coding prediction value, also serves to specify the direction for obtaining estimated values for error concealment. An interpolation filter defines the manner of obtaining estimated pixel values along the direction specified by the intra-prediction mode. Like the intra-prediction mode, the interpolation filter is derived in accordance with the coding of the image. Concealment of the image is achieved using the estimated values obtained in the manner prescribed by the interpolation filter.
