  • Predictive motion vector coding
    Patent number: 9667993
    Abstract: Overlapped block disparity estimation and compensation is described. Compensating for images with overlapped block disparity compensation (OBDC) involves determining if OBDC is enabled in a video bit stream, and determining if OBDC is enabled for one or more macroblocks that neighbor a first macroblock within the video bit stream. The neighboring macroblocks may be transform coded. If OBDC is enabled in the video bit stream and for the one or more neighboring macroblocks, predictions may be made for a region of the first macroblock that has an edge adjacent with the neighboring macroblocks. OBDC can be causally applied. Disparity compensation parameters or modes may be shared amongst views or layers. A variety of predictions may be used with causally-applied OBDC.

  • Method of bit allocation for image and video compression using perceptual guidance
    Patent number: 9661328
    Abstract: A video processing system is provided to create quantization data parameters based on human eye attraction to provide to an encoder to enable the encoder to compress data taking into account the human perceptual guidance. The system includes a perceptual video processor (PVP) to generate a perceptual significance pixel map for data to be input to the encoder. Companding is provided to reduce the pixel values to values ranging from zero to one, and decimation is performed to match the pixel values to a spatial resolution of quantization parameter values (QP) values in a look up table (LUT). The LUT table values then provide the metadata to provide to the encoder to enable compression of the original picture to be performed by the encoder in a manner so that bits are allocated to pixels in a macroblock according to the predictions of eye tracking.

  • Adaptive transform size selection for geometric motion partitioning
    Patent number: 9654776
    Abstract: In one example, an apparatus includes a video encoder configured to partition a block of video data into a first geometric partition and a second geometric partition using a geometric motion partition line, wherein the block comprises N×N pixels, divide the block of video data into four equally-sized, non-overlapping (N/2)×(N/2) sub-blocks, and encode at least one of the sub-blocks through which the geometric motion partition line passes using a transform size smaller than (N/2)×(N/2).

  • Real time video summarization
    Patent number: 9639762
    Abstract: System, apparatus, method, and computer readable media for on-the-fly captured video summarization. A video stream is incrementally summarized in concurrence with generation of the stream by a camera module. Saliency of the video stream summary is maintained as the stream evolves by updating the summary to include only the most significant frames. In one exemplary embodiment, saliency is determined by optimizing an objective function including terms that are indicative of both the diversity of a selection, and how representative the selection is to the processed portion of the video data corpus. A device platform including a CM and comporting with the exemplary architecture may provide video camera functionality at ultra-low power, and/or with ultra-low storage resources, and/or with ultra-low communication channel bandwidth.

  • Coding format converter partially halting search for coding candidates
    Patent number: 9635372
    Abstract: A coding format converter for converting an input stream of data of pictures of a first coding format into a data stream of data of pictures with a second coding format includes a decoder decoding the input stream with the first coding format, an encoder encoding the data of the picture thus decoding with the second coding format, a coding candidate search controller using first information on prediction residual availability indicative of whether or not residual information is encoded for each block in the decoded picture. When a search for coding candidates reveals a result that the first information for a coding target region of the picture is indicative of the absence of a residual, the controller refrains from searching for coding candidates which depend on second information on residual availability of the coding with the second coding format.

  • Emulation of Bi predicted pictures using adjacent pictures for improved video
    Patent number: 9621892
    Abstract: A method and apparatus for emulation of Bi predicted B pictures is described where a B picture is constructed only from information from one preceding and successive frame without pixel averaging or motion vector computation. In the case of H.264 or analogous codecs, a top field of a B picture is formed from the successive I or P picture top field, and the bottom field formed from the previous P picture bottom field. B picture emulation may reverse the previous and successive pictures. For interlaced pictures, the odd and ever interlacing fields are treated as top and bottom fields, and also use information from both one preceding and successive frame. The resulting Bi predicted B pictures reduce inter-GOP flicker.
