Abstract: When dependent scalar quantization is used, the choice of the quantizer depends on the decoding of the preceding transform coefficient, and the entropy decoding of a transform coefficient depends on quantizer choice. To maintain high throughput in hardware implementations for transform coefficient entropy coding, several decision schemes of the scaler quantizer are proposed. In one implementation, the state transition and the context model selection are based on only regular coded bins. For example, the state transition can be based on the sum of the SIG, gt1 and gt2 flags, the exclusive-or function of the SIG, gt1 and gt2 flags, or based on only the gt1 or gt2 flag. When a block of transform coefficients is coded, the regular mode bins can be coded first in one or more scan passes, and the remaining bypass coded bins are grouped together in another one or more scan passes.

Abstract: For each image in a set of images, residual data is obtained based on first and second representations of the image at a first level of quality. The second representation is based on a representation of the image at a second, lower level of quality. The residual data is useable by a decoder to reconstruct, for each image in the set, the first representation using the second representation. One or more configuration parameters of configuration data relating to processing of the residual data: (i) are obtained, (ii) are useable by the decoder to reconstruct the first representation for each image in the set, and (iii) correspond to multiple images in the set. The one or more configuration parameters are output for processing by the decoder. The number of times the one or more configuration parameters is output for the set is less than the number of images in the set.

Abstract: Various examples are provided related to generation of accurate measurement information for a structure including a building of interest. A single passive image capture device (e.g., handheld devices such as cellular telephones and tablets) can generate two-dimensional (2D) images that overlap with regard to a building element of interest.

The extracted information can be used in applications such as construction/remodeling estimation, 3D model generation, insurance policy underwriting and adjusting, interior design efforts, landscaping, real estate marketing, inventory management and other areas where it can be desirable to obtain information about features and dimensions of one or more features or objects present in the location.

Abstract: A method of signaling additional chroma QP offset values that are specific to quantization groups is provided, in which each quantization group explicitly specifies its own set of chroma QP offset values. Alternatively, a table of possible sets of chroma QP offset values is specified in the header area of the picture, and each quantization group uses an index to select an entry from the table for determining its own set of chroma QP offset values. The quantization group specific chroma QP offset values are then used to determine the chroma QP values for blocks within the quantization group in addition to chroma QP offset values already specified for higher levels of the video coding hierarchy.

Abstract: According to an aspect, a video encoder selects a block of intermediate size from a set of block sizes for intra-prediction estimation for encoding a video signal. A set of neighbouring blocks with the intermediate size are tested for combining. If the set of neighbouring blocks are determined to be combinable, the video encoder selects a larger block size formed by the tested neighbouring blocks for encoding. On the other hand, if the set of neighbouring blocks are determined to be not combinable, the video encoder selects a smaller block size from the set of tested neighbouring blocks for prediction. According to another aspect, the best mode for intra-prediction is determined by first intra-predicting a block with intermediate modes in a set of modes. Then the intra-predictions are performed for the neighbouring modes of at least one intermediate mode.

Abstract: An encoder encodes transform coefficients of a transform coefficient block representing a block of a picture using a scan pattern which sequentially traverses the transform coefficients of the transform block by encoding absolute values of quantization levels of the transform coefficients. The absolute values are binarized with a binarization comprising a first part of the binarization below a cutoff value and a second part of the binarization, prefixed by a codeword of the first part of the binarization for the cutoff value, above the cutoff value. The encoder adaptively, based on previously encoded transform coefficients, decreases the cutoff value to zero monotonically during encoding of the transform coefficients so that the binarization comprises the second part of the binarization and not the first part of the binarization.

Abstract: A video decoder decodes a first indication (190) indicating whether transform coefficients of a first transform coefficient block (921) corresponding to a first color component are encoded into a data stream. The decoder also decodes a second indication (190) indicating whether transform coefficients of a second transform coefficient block (922) corresponding to a second color component are encoded into the data stream using context-adaptive entropy decoding with a context selected based on the first indication for the first transform coefficient block (921). The decoder further derives a block (84) of the picture by, separately for the first color component and the second color component, a reverse transformation of the first transform coefficient block (921 and the second transform block (922, respectively.
