Abstract: A video block syntax element indicates whether all of the partitions of a video block are predicted based on a same reference list and no greater than quarter-pixel accuracy is used. If the video block syntax element is set, partition-level signaling of the reference lists is avoided. If the video block syntax element is not set, partition-level signaling of the reference lists occurs. If the video block syntax element is set, partition-level syntax elements may be used for each of the partitions of the video block, wherein the partition-level syntax elements each identify one of the reference lists and motion vector accuracy for a given one of the partitions.

Abstract: Methods, circuits, and systems for time encoder-based unmixing of hyperspectral imaging data are disclosed. A method of unmixing hyperspectral imaging data includes receiving mixed image data of one or more pixels. The mixed image data is generated by an imaging device that captures hyperspectral data. The mixed image data includes sensed spectral band intensities of materials in an area represented by a particular pixel. The mixed image data is converted from first analog domain signals into pulse domain signals. A solution to a mixing equation in the pulse domain is generated to identify abundances of one or more of the materials based on the sensed spectral band intensities. The sensed spectral band intensities are compared to reference spectral band intensities of a set of considered materials. The solution is converted from a pulse domain into an analog domain as second analog domain signals.

Abstract: An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below. The present invention is applied to an encoder for encoding image information and a decoder for decoding image information.

Abstract: Video signal coding apparatus includes a quantization unit which quantizes a luminance signal of each of a first picture and a second picture coded after the first picture, and quantizes a chrominance signal of each of the first picture and the second picture. A code amount obtainment unit obtains a luminance code amount and a chrominance code amount of each of the first picture and the second picture; and a rate calculation unit calculates a rate of the chrominance code amount with respect to the luminance code amount for each of the first picture and the second picture. A rate control unit changes a coefficient value of at least one of the first matrix and the second matrix used in quantizing the second picture, before the quantization unit quantizes the second picture, so that the rate for the second picture becomes smaller than the rate for the first picture.

Abstract: With use of a simplified program or calculating device for motion compensation, a video decoding device decodes video data compressed by motion detection operations on macroblock units, as in the MPEG-4AVC standard. The video decoding device splits compressed data blocks of the prescribed size, 16×16 pixels for instance, to generate sub-blocks, which are smaller than the blocks and on which the video decoding device is able to execute motion compensation operations. The video decoding device duplicates a motion vector assigned to a given block to generate as many motion vectors as there are sub-blocks in the given block, and executes motion compensation on each sub-block using the corresponding duplicate motion vector. Data resulting from the motion compensation operation on each sub-block is combined to obtain a target block corresponding to the given block.
