    摘要: Filtering lower quality images or sequences of images with higher quality images or sequences of images. The filtering is utilized in a post-process, decoded, or encoded images including multiple sets of images that are filtered and/or combined. Different image features including, for example, quality, frequency characteristics, temporal resolution, spatial resolution, number of views, or bit-depth are present in the images. In one embodiment, the filtering comprises a multi-hypothesis filtering and the confidence value comprises a difference between the filtered sample and samples lying within a filter support. The post processes images are then stored or distributed.

    摘要: An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bit-stream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.
