Overview
JPEG-LS is an image compression scheme and file format. It supports both lossy and lossless compression. The lossy compression is often called "near-lossless", because the encoder can set a limit on the maximum error. Its compression algorithm is LOCO-I, developed by HP Labs.
Disambiguation
The file format is similar in structure to JPEG interchange format, and it was developed by the same organization that developed JPEG. Beyond that, JPEG-LS is not closely related to JPEG.
Beware of documents which confuse the term "JPEG-LS" with the term "Lossless JPEG". See Lossless JPEG for more information.
Related formats
JPEG-LS compression can be used in some other file formats, such as JPX, JPM, SPIFF, and DICOM.
