0 not involving the loss of data or electrical energy: --
Lossless compression algorithms reduce file size with no loss in image quality.
Lossless compression reduces bits by identifying and eliminating statistical redundancy.
Lossless compression is preferred for archival purposes and often for medical imaging, technical drawings, clip art, or comics.
After the removal of these details, lossless compression can be applied to the remainder to greatly reduce the file size.
With a quantization step that equals 1, no quantization is performed (it is used in lossless compression).
Modern systems tend to store the data digitally, often with lossless compression.
Lossless compression methods may be categorized according to the type of data they are designed to compress.
It is an inherently lossless compression technique, like almost all entropy-coders.
This is in contrast with lossless data compression, where data will not be lost via the use of such a procedure.
