  • Patent number: 10382783
    Abstract: A decoding device includes a decoder that decodes information of a direction of intra-picture prediction of a target block and compression data of a residual signal, a prediction signal generator that generates an intra-picture prediction signal using the information of the direction and an previously reconstructed reference sample of an adjacent block, a residual signal restorator that restores a reconstructed residual signal of the target block, and a block storage that restores and stores a pixel signal of the target block. The prediction signal generator derives reference samples from a previously reconstructed block neighbouring the target block stored, selects two or more key reference samples, performs an interpolation process between the key reference samples for generating interpolated reference samples, and generates the intra-picture prediction signal by extrapolating the interpolated reference samples based on the direction of the intra-picture prediction.

  • Patent number: 10362317
    Abstract: Although wedgelet-based partitioning seems to represent a better tradeoff between side information rate on the one hand and achievable variety in partitioning possibilities on the other hand, compared to contour partitioning, the ability to alleviate the constraints of the partitioning to the extent that the partitions have to be wedgelet partitions, enables applying relatively uncomplex statistical analysis onto overlaid spatially sampled texture information in order to derive a good predictor for the bi-segmentation in a depth/disparity map. Thus, in accordance with a first aspect it is exactly the increase of the freedom which alleviates the signaling overhead provided that co-located texture information in form of a picture is present. Another aspect pertains the possibility to save side information rate involved with signaling a respective coding mode supporting irregular partitioning.

  • Patent number: 10349056
    Abstract: For an image portion to encode an initial set of motion information predictors is obtained. It is tested whether the number of motion information predictors in the initial set is lower than a target number and, if so, one or more motion information predictors are added to the initial set to generate a set of motion information predictors having controlled diversity. The motion information predictors of the initial set are actual motion information predictors, having motion vectors obtained from image portions of the image being encoded or of a reference image, and potential motion information predictors for addition include one or more further such actual motion information predictors and also include one or more virtual motion information predictors not having motion vectors obtained from image portions of said image being encoded or of a reference image. A motion information predictor for the image portion to encode is selected from the generated set of motion information predictors.

  • Patent number: 10334255
    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: 10321163
    Abstract: A VP8 video decoder is implemented by partitioning the required functions across multiple sub systems, with an optimal mapping to existing functional blocks. Key optimizations include the reuse of hardware designed for prior generation VP6 and VP7 decoders. In order to reduce implementation complexity, cost and power consumption, a non-exact, approximate deblocking loop filter is implemented.

  • 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: 10288879
    Abstract: An image of an eye of a user can be received from an image sensor, the image resulting from the image sensor detecting light from one or more illuminators reflected from the eye of the user and reflected from optic arrangements located between the one or more illuminators and the eye of the user, wherein the optic arrangements comprise features having a known pattern. Glints are identified in the image, wherein a glint is a representation in the image of a reflection of light from a cornea of the eye of the user and/or from a feature of the optic arrangements. Relative positions in the image of the identified glints are determined, and on condition that the relative positions conform with the known pattern, at least one glint of the identified glints is identified as a representation in the image of a reflection from a feature of the optic arrangements.

  • Patent number: 10264269
    Abstract: In a coding system, an encoder codes video data according to a predetermined protocol, which, when decoded causes an associated decoder to perform a predetermined sequence of decoding operations. The encoder may perform local decodes of the coded video data, both in the manner dictated by the coding protocol that is at work and also by one or more alternative decoding operations. The encoder may estimate relative performance of the alternative decoding operations as compared to a decoding operation that is mandated by the coding protocol. The encoder may provide identifiers in metadata that is associated with the coded video data to identify such levels of distortion and/or levels of resources conserved. A decoder may refer to such identifiers when determining when to engage alternative decoding operations as may be warranted under resource conservation policies.

  • Patent number: 10250886
    Abstract: A prediction information derivation unit derives inter prediction information candidates from inter prediction information of coded prediction blocks neighboring a prediction block subject to coding within the same picture as the prediction block subject to coding and inter prediction information of a prediction block in a coded picture that is different from the prediction block subject to coding. The prediction information derivation unit determines an inter prediction information candidate to be used for inter prediction of the prediction block subject to coding from the inter prediction information candidates that have been derived. A second bitstream generation uni codes an index that indicates the inter prediction information candidate based on the number of the inter prediction information candidates.
