Abstract: A method for processing of motion images based on a first set of motion image frames for a first eye view and at least one image frame for a second eye view. One embodiment of the method can include: identifying an object in a first image frame from the first eye view at a given time t; using a planar tracker, generating a homography relating to apparent movement of the object between the first image frame from the first eye view at the given time to a first image frame from the second eye view at a similar time t?; and using the homography to enhance processing of image(s) in the first and/or the second eye view. Thus, the homography can be used to define the relationship between two views taken at a similar time from two different locations.

Abstract: Innovations described herein provide a generic encoding and decoding framework that includes some features of simulcast and some features of scalable video coding. For example, a bitstream multiplexer multiplexes component bitstreams into a multi-layer encoding (MLE) bitstream that provides temporal scalability, spatial resolution scalability and/or signal to noise ratio scalability. Each of the component bitstreams provides an alternative version of input video, and a given component bitstream can be a non-scalable bitstream or scalable bitstream. The multiplexer follows composition rules for the MLE bitstream and may rewrite values of certain syntax elements of component bitstreams using an approach that avoids bit shifting operations. A corresponding demultiplexer receives an MLE bitstream that includes component bitstreams and demultiplexes at least part of at least one of the component bitstreams from the MLE bitstream, following decomposition rules for the demultiplexing.

Abstract: In for example the assignment of motion vectors, an array of pixel-to-pixel dissimilarity values is analyzed to identify a pixel which has a low pixel-to-pixel dissimilarity value and which has neighboring pixels which have a low pixel-to-pixel dissimilarity value. The pixel-to-pixel dissimilarity values are filtered with a filter aperture decomposed into two or more sectors with partial filters applied respectively to each sector. Outputs of the partial filters are combining by a non-linear operation, for example taking the minimum from diametrically opposed sectors.
