Abstract: Processing a reference picture is described. A reference processing unit enables signaling of parameters such as motion model parameters, interpolation filter parameters, intensity compensation parameters, and denoising filter parameters. Methods for estimating the various parameters are also discussed. Processing improves quality of a reference picture prior to its use for prediction of a subsequent picture and thus improves the prediction.

Abstract: Enhancement methods for sampled and multiplexed image and video data are described. Each component picture is separately processed either after de-multiplexing or on the fly. Processing and de-multiplexing can be combined in a single joint step. The methods apply to both encoding and decoding system and include applications to scalable video coding systems.

Abstract: 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.

Abstract: Controlling a feature of an encoding process for regions of an image pattern representing more than one image when the regions include an amount of disparity in the represented images that would result in cross-contamination between the represented images if encoded with the feature. The control may be, for example, any of, turning the encoding feature off, using the encoding feature less often than when encoding an image pattern representing a single image, negatively biasing the encoding feature, and enabling the encoding feature for regions determined to have zero or near zero disparity and disabling the feature for all other regions. The represented images comprise, for example, any of a stereoscopic view, multiple stereoscopic views, multiple views of a same scene, and multiple unrelated views.

Abstract: Stereoscopic images are subsampled and placed in a "checkerboard" pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the "checkerboard" is decoded. Portions of the checkerboard (e.g., "black" portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., "white" portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.
