A method for processing information from an IR detector of an IR camera, for an embodiment, comprises receiving a series of frames of data from said IR detector being operable to detect IR radiation from a scene, said frames of IR data representing detected IR radiation; performing a compression of said frames of IR data; wherein each data value together with calibration data uniquely represents measured IR radiation from the scene.

An image coding apparatus obtains a quantization parameter of a macroblock to be encoded. The quantization parameter is corrected by adding a correction value thereto. An encoding part encodes the macroblock by using the corrected quantization parameter. After the encoding, a quantization parameter correction part calculates the cumulative target amount of codes by accumulating the target amounts of codes set for the encoded macroblocks, respectively, and calculates the cumulative amount of generated codes by accumulating the respective amounts of generated codes of the encoded macroblocks. If the cumulative amount of generated codes is larger than the cumulative target amount of codes, the quantization parameter correction part increments the correction value. A new macroblock to be encoded is quantized more coarsely than the encoded macroblocks.

A system implements rate control for encoding and decoding operations, for example, operations performed on slices of data such as image data. The system implements fine-grained bit rate control allowing for non-integer bit rates to be specified for the system. The non-integer values may allow the system to more accurately characterize a data rate of a communication link between a source and sink. The more accurate characterization may facilitate improved utilization of the communication link capacity.

Techniques are described where a device that includes a video decoder outputs information identifying a picture to a device that includes a video encoder. The video encoder may determine pictures that could have been used to inter-prediction encode the identified picture and/or pictures following the identified picture in coding order. The video encoder may inter-prediction encode a current picture based on one or more of the determined pictures and/or the identified picture.

For a decoding apparatus based on H.265/HEVC with single-core or single-threaded hardware not parallelized, which executes decoding a plurality of tiles and filtering around a tile boundary, the disclosed invention is intended to reduce the frequency of access to decoded data around the boundaries between tiles stored in a frame memory for filtering such data or reduce the circuit size of a buffer that retains decoded data around the boundaries between tiles. The image decoding apparatus disclosed herein executes decoding and filtering in raster scan order across a screen independently of the sizes and positional relations of tiles. At a tile boundary, decoding proceeds to a right adjacent tile on the same row, rather than decoding coding blocks on one row down in the same tile, and filtering is also executed using decoded data of row-wise adjacent coding blocks.

Methods and apparatus for coding video information having a plurality of video samples are disclosed. Blocks for video data are coded by an encoder based upon a quantization parameter (QP) for each block. The video data may be coded in a particular color space, such as YCoCg, wherein different QP values may be used for coding different color components of the video data. Because the human eye is generally more sensitive to differences in luma compared to chroma, and more sensitive to differences in chromatic green than chromatic orange, when the YCoCg color space is used to code the video data, different QP values may be determined for each color component channel. By coding each color component using different QP values, loss from quantization may be reduced while also reducing the appearance of visual artifacts in the coded video data.
