  • Patent number: 9936198
    Abstract: In a moving picture coding device that further divides a first block acquired by dividing each picture of a moving picture into a predetermined size into one or a plurality of second blocks and codes the moving picture in units of blocks, a quantization parameter calculation unit calculates a quantization parameter of the second block. A predictive quantization parameter deriving unit derives a predictive quantization parameter of the second block by using the quantization parameter of one or a plurality of third blocks that are neighboring to the second block. The predictive quantization parameter deriving unit derives the predictive quantization parameter of the second block by using a quantization parameter of a fourth block coded before the second block in a case where the third block neighboring to the second block is located at a position beyond a boundary of the first block.

  • Patent number: 9924194
    Abstract: A motion vector predictor candidate constructing unit performs prediction based on a motion vector of one of coded blocks neighboring a coding target block in the same picture as the coding target block, constructs a plurality of motion vector predictor candidates, and adds the motion vector predictor candidates to a motion vector predictor candidate list. A motion vector predictor candidate number limiting unit limits the number of motion vector predictor candidates added to the motion vector predictor candidate list to a maximum candidate number according to a size of a prediction block. A motion vector predictor selecting unit selects a motion vector predictor from the motion vector predictor candidate list. A coding unit codes information representing an index of the selected motion vector predictor in the motion vector predictor candidate list.

  • Patent number: 9918103
    Abstract: A prediction information deriving unit derives the inter-prediction information candidates from inter-prediction information of a prediction block neighboring to a coding target prediction block or a prediction block present at the same position as or near the coding target prediction block in a coded picture at a temporally different position from the coding target prediction block. A candidate supplementing unit supplements inter-prediction information candidates having the same prediction mode, reference index, and motion vector until the number of inter-prediction information candidates reaches the designated number of candidates when the number of inter-prediction information candidates is smaller than the designated number of candidates.

  • Patent number: 9906796
    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.

  • Patent number: 9906810
    Abstract: In inter prediction that is performed by partitioning a first block, which is obtained by partitioning each picture, into one or more second blocks, a spatial merge candidate generating unit derives a spatial merge candidate without referring to a block included in a first block that includes a second block. In case of a mode where a coding block is divided by a horizontal border into prediction blocks arranged vertically, the reference index derivation unit of a time merge candidate sets reference index information of a time merge candidate to a value of reference index information of an encoded prediction block adjacent to a left edge of a prediction block subject to encoding.

  • Patent number: 9894255
    Abstract: A method and a system for depth selective segmentation of an object are provided. The method comprises the following steps. An image is captured in an invisible domain of the optical spectrum by illuminating a scene of interest under an illumination corresponding to said invisible domain of the optical spectrum by an invisible light illumination unit. A binary mask is obtained from the image according to a threshold. Part of the image is eliminated by applying the binary mask to the image, and resulting in another image. The threshold is changed and another binary mask is obtained. The latest obtained binary mask is applied to the latest captured image. The step of changing of the threshold, the step of obtaining a mask and the step of applying the latest obtained binary mask on the latest captured image are performed at least once.
