摘要： Methods and apparatus for lossless LiDAR LAS file compression and decompression are provided that include predictive coding, variable-length coding, and arithmetic coding. The predictive coding uses four different predictors including three predictors for x, y, and z coordinates and a constant predictor for scalar values, associated with each LiDAR data point.

摘要： The technology in this application compresses multi-antenna complex-valued signals by exploiting both a spatial and a temporal correlation of the signals to remove redundancy within the complex-valued signals and substantially reduce the capacity requirement of backhaul links. At a receiver, the compressed signal is received, and a decompressor decompresses the received signal over space and over time to reconstruct the multiple antenna stream.

摘要： A data processing apparatus for compressing physical address values correlated to logical address values includes a first prediction unit that calculates a first predicted address value for a first input address value in input data to be compressed, a determination unit that selects an encoding processing for the first input address value according to the first predicted address value, and a compression unit configured to encode the first input address value according to the encoding processing selected by the determination unit.

摘要： Methods and devices are described for entropy coding data using an entropy coder to encode quantized transform domain coefficient data. Last significant coefficient information is signaled in the bitstream using two-dimensional coordinates for the last significant coefficient. The context for bins of one of the coordinates is based, in part, upon the value of the other of the coordinates. In one case, instead of signaling last significant coefficient information, the number of non-zero coefficients is binarized and entropy encoded.

摘要： An image compression scheme is disclosed which models the human visual perception system. Using quantization of image error values, according to a visually-lossless scheme, an image can be compressed such that it is visually indistinguishable to the naked eye from the original image. To aid in image compression on portable devices such as a digital camera, the quantization can be precoupled into a look-up table.

摘要： Methods and systems may include a compression module having logic to receive a pixel difference signal associated with an image, and conduct a compression of the pixel difference signal based on a value of the pixel difference signal. The logic can also generate a modified pixel difference signal based on the compression, wherein the compression may enable the image to be stored to dynamic random access memory (DRAM) in a compressed state.
