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： Embodiments feature families of rate allocation and rate control methods that utilize advanced processing of past and future frame/field picture statistics and are designed to operate with one or more coding passes. At least two method families include: a family of methods for a rate allocation with picture look-ahead; and a family of methods for average bit rate (ABR) control methods. At least two other methods for each method family are described. For the first family of methods, some methods may involve intra rate control. For the second family of methods, some methods may involve high complexity ABR control and/or low complexity ABR control. These and other embodiments can involve any of the following: spatial coding parameter adaptation, coding prediction, complexity processing, complexity estimation, complexity filtering, bit rate considerations, quality considerations, coding parameter allocation, and/or hierarchical prediction structures, among others.

摘要： Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.

摘要： Multi-layer encoding and decoding systems and methods are provided. A processing module processes outputs of a first base or enhancement layer and sends the processed outputs to a second, enhancement layer. Operation of the processing module is controlled, so that the second layer can receive processed or unprocessed outputs of the first layer in accordance with the circumstances. Processing of the outputs of the first layer can occur together with or separately from a disparity compensation process.
