  • Patent number: 10321148
    Abstract: In accordance with a first aspect, the intra prediction direction of a neighboring, intra-predicted block is used in order to predict the extension direction of the wedgelet separation line of a current block, thereby reducing the side information rate necessitated in order to convey the partitioning information. In accordance with a second aspect, the idea is that previously reconstructed samples, i.e. reconstructed values of blocks preceding the current block in accordance with the coding/decoding order allow for at least a prediction of a correct placement of a starting point of the wedgelet separation line, namely by placing the starting point of the wedgelet separation line at a position of a maximum change between consecutive ones of a sequence of reconstructed values of samples of a line of samples extending adjacent to the current block along a circumference thereof. Both aspects may be used individually or in combination.

  • Patent number: 10321139
    Abstract: The way of predicting a current block by assigning constant partition values to the partitions of a bi-partitioning of a block is quite effective, especially in case of coding sample arrays such as depth/disparity maps where the content of these sample arrays is mostly composed of plateaus or simple connected regions of similar value separated from each other by steep edges. The transmission of such constant partition values would, however, still need a considerable amount of side information which should be avoided. This side information rate may be further reduced if mean values of values of neighboring samples associated or adjoining the respective partitions are used as predictors for the constant partition values.

  • Patent number: 10204423
    Abstract: Disclosed are techniques for more accurately estimating the pose of a camera used to capture a three-dimensional scene. Accuracy is enhanced by leveraging three-dimensional object priors extracted from a large-scale three-dimensional shape database. This allows existing feature matching techniques to be augmented by generic three-dimensional object priors, thereby providing robust information about object orientations across multiple images or frames. More specifically, the three-dimensional object priors provide a unit that is easier and more reliably tracked between images than a single feature point. By adding object pose estimates across images, drift is reduced and the resulting visual odometry techniques are more robust and accurate. This eliminates the need for three-dimensional object templates that are specifically generated for the imaged object, training data obtained for a specific environment, and other tedious preprocessing steps.

  • Patent number: 10110925
    Abstract: A method of video coding utilizing ARP (advanced residual prediction) by explicitly signaling the temporal reference picture or deriving the temporal reference picture at the encoder and the decoder using identical process is disclosed. To encode or decode a current block in a current picture from a dependent view, a corresponding block in a reference view corresponding to the current block is determined based on a DV (disparity vector). For the encoder side, the temporal reference picture in the reference view of the corresponding block is explicitly signaled using syntax element(s) in the slice header or derived using an identical process as the decoder. For the decoder side, the temporal reference picture in the reference view of the corresponding block is determined according to the syntax element(s) in the slice header or derived using an identical process as the decoder. The temporal reference picture is then used for ARP.

  • Patent number: 10075700
    Abstract: The present disclosure improves 3D representation (by means of adjusting disparity between pictures) in stereoscopic or autostereoscopic images in order to better fit the natural viewing geometry by modifying each image of a stereo pair with a geometric transform centered on an intersection point of an imaging plane and a gaze direction for each of eyes. An observer's view is modeled independently for the left and right eyes, and the left and right views are processed independently with the goal to re-align pixel directions for each of eyes to make these directions more in correspondence with natural vision for the observer.
