Methods and apparatus are provided for sparsity-based de-artifact filtering for video encoding and decoding. An apparatus includes an encoder (400) for encoding at least a portion of an image by grouping regions within the portion based on a grouping metric, transforming the grouped regions, adaptively performing de-artifact filtering on the transformed regions using a de-artifacting filter (413) included in the encoder, inverse transforming the de-artifacted regions to create replacement regions, and restoring the replacement regions to positions with the image from which the regions were taken prior to the grouping.

Methods and apparatus are provided for implicit adaptive motion vector predictor selection for video encoding and decoding. The method encodes an image block using implicit adaptive motion vector predictor selection. The motion vector for encoding the block is predicted by defining a set of motion vector predictor candidates for the block based on a plurality of spatio-temporal neighboring motion vectors; and then selecting from the set a particular motion vector predictor candidate as the motion vector for encoding the bloc. The selection is made responsive to respective values for a fidelity of the spatio-temporal neighboring motion vectors.

Methods and apparatus are provided for adaptive motion vector candidate ordering for video encoding and decoding. An apparatus includes a video encoder for encoding a block in a picture by selecting an order of motion vector predictor candidates for the block responsive to a characteristic available at both the video encoder and a corresponding decoder. The characteristic excludes a mode in which the block is partitioned.

There are provided method and apparatus for use in a multi-view video coding system. The apparatus includes an encoder for encoding at least two views corresponding to multi-view video content into a resultant bitstream, wherein the resultant bitstream is encoded to include view specific information. The view specific information indicates a decoding interdependency between at least some of the at least two views.

There are provided methods and apparatus for transform selection in video coding. An apparatus includes a video encoder for encoding at least a block in a picture by selecting a transform to apply to a residue of the block from a set of two or more available transforms. The transform is selected based on at least one of an inter prediction mode used to predict at least one reference for the block, one or more values corresponding to a motion vector, a value of a residue of one or more previously encoded blocks, a value of prediction data for the block, one or more transform selections of one or more neighboring reconstructed blocks, and a quantization step applied to transform coefficients for the residue of the block.

There are provided method and apparatus for filter parameter determination and selection responsive to variable transforms in sparsity-based de-artifact filtering. An apparatus includes an encoder for encoding picture data for at least a portion of a picture. The encoder includes a sparsity-based de-artifact filter for performing sparsity-based de-artifact filtering on the portion. One or more filter parameters for the sparsity-based de-artifact filtering are determined and selected responsive to variable transforms.

The present embodiments relate to engineering imaging probes based on “triggered molecular geometry.” Upon detection of a molecular signal, nucleic acid hairpin monomers assemble an imageable molecular shape with prescribed geometry. In some embodiments the prescribed shape can be imaged directly. In some embodiments, the prescribed shape can serve as a spatial organizer or amplification scheme for other imaging entities, such as fluorophore and fluorescent proteins.

The invention provides nucleic acid structures of controlled size and shape, comprised of a plurality of oligonucleotides, and methods for their synthesis. The structures are formed, at least in part, by the self-assembly of single stranded oligonucleotides. The location of each oligonucleotide in the resultant structure is known. Accordingly, the structures may be modified with specificity.

Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture, accessing information indicating how the multiple pictures in the accessed video picture are combined, decoding the video picture to provide a decoded representation of at least one of the multiple pictures, and providing the accessed information and the decoded video picture as output. Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.

A remote control device is operative to enable and facilitate user control of video systems that are operative to provide one or more three-dimensional (3D) viewing effects. According to an exemplary embodiment, the remote control device includes a user input terminal having an input element operative to receive user inputs to adjust at least one of a volume setting and a channel setting of a video system, and further operative to receive user inputs to adjust a three-dimensional (3-D) viewing effect of the video system. A transmitter is operative to transmit control signals to the video system in response to the user inputs.
