LOSSLESS COMPRESSION OF FRAGMENTED IMAGE DATA

摘要

Lossless compression of fragmented image data is disclosed. In some embodiments, a stream of information is received, wherein the stream of information comprises a sequence of tuples and wherein each of the tuples comprises data elements corresponding to one of a plurality of input channels. A channel transformer is employed to rearrange the data elements into a plurality of output channels for an output stream wherein the output channels have higher compressibility than the input channels. The compressed output stream is stored.

1. A system, comprising:
a processor configured to:
receive an input sequence of data comprising a first channel;generate a second channel based at least in part on a transform of data of the first channel;generate a compressed output by encoding the second channel with a variable length code adapted to statistics of the data elements of the second channel, wherein the compressed output is based on a selection of one or more thresholds according to data elements of the second channel; and a memory that stores the compressed output.
