    摘要: There are provided methods and apparatus for edge-based spatio-temporal filtering. An apparatus for filtering a sequence of pictures includes a spatial filter, a motion compensator, a deblocking filter, and a temporal filter. The spatial filter is for spatially filtering a picture in the sequence and at least one reference picture selected from among previous pictures and subsequent pictures in the sequence with respect to the picture. The motion compensator, in signal communication with the spatial filter, is for forming, subsequent to spatial filtering, multiple temporal predictions for the picture from the at least one reference picture. The deblocking filter, in signal communication with the motion compensator, is for deblock filtering the multiple temporal predictions. The temporal filter, in signal communication with the deblocking filter, is for temporally filtering the multiple temporal predictions and combining the multiple temporal predictions to generate a noise reduced version of the picture.

    摘要: Conversion of interleaved data and/or correction of color samples or other data are corrected by recognizing an underlying arrangement or format of different data sets within a data stream and a conversion process applied that causes bleeding between the sets The data sets are, for example, separate channel views of a 3D display, and the corruption occurs, for example, upon up-conversion of color samples that take into account both views together rather than individually. The invention is embodied, for example, as part of a playback device, display, or as a stand alone converter box that corrects the corrupted samples by at least one of substitution, filtering, or interpolation with appropriately selected samples (e.g., neighboring samples of a same view). In one embodiment, the invention comprises a conversion from a received format (e.g., checkerboard) to a delivery format (e.g., native format of a 3D ready display).

    摘要: Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

    摘要: There is disclosed a video encoder and corresponding method for encoding video data for an image block. The video encoder performs a mode decision by performing initial motion estimation on only a subset of possible block sizes to output motion information corresponding thereto, and determining, based upon the motion information corresponding to only the subset of possible of block sizes and upon other image-related analysis data, whether other block sizes are to be evaluated.

    摘要: A decoding arrangement for decoding pictures in an incoming video stream includes a noise generator for adding a dither signal containing random noise to the pictures after video decoding, to improve the subjective video quality. The noise generator adds noise to each pixel in an amount correlated to the luminance of at least a portion of the current picture.
