  • Patent number: 10885632
    Abstract: Cameras may be used to acquire information about objects in three-dimensional (3D) space. Described herein are techniques for determining a calibration between pixel coordinates in a two-dimensional image acquired by the camera and coordinates in the 3D space. In one implementation, the target assembly is positioned at a known 3D location and particular optical targets thereon having known 3D coordinates are activated sequentially. Images are acquired and processed to determine the pixel coordinates of the respective optical targets. Calibration data, such as a transformation matrix, is generated based on the information about which optical target is active in a given acquired image, the pixel coordinates of the optical target in that acquired image, and the known 3D coordinates of the individual optical target.

  • Patent number: 10848785
    Abstract: Deblocking filtering is provided in which an 8×8 filtering block covering eight sample vertical and horizontal boundary segments is divided into filtering sub-blocks that can be independently processed. To process the vertical boundary segment, the filtering block is divided into top and bottom 8×4 filtering sub-blocks, each covering a respective top and bottom half of the vertical boundary segment. To process the horizontal boundary segment, the filtering block is divided into left and right 4×8 filtering sub-blocks, each covering a respective left and right half of the horizontal boundary segment. The computation of the deviation d for a boundary segment in a filtering sub-block is performed using only samples from rows or columns in the filtering sub-block. Consequently, the filter on/off decisions and the weak/strong filtering decisions of the deblocking filtering are performed using samples contained within individual filtering blocks, thus allowing full parallel processing of the filtering blocks.

  • Patent number: 10841608
    Abstract: A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to activation of merging and activation of the skip mode. One possible state of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. A common flag may signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.
