About:
CharLS is a high-performance, open-source C++ library that implements the JPEG-LS standard for lossless and near-lossless image compression. It provides a robust API for developers to efficiently compress and decompress medical and scientific imagery. Its primary value is delivering superior compression ratios for 16-bit data while maintaining full fidelity.

Key Features:

High-performance C++ implementation
Lossless and near-lossless compression
Conforms to the JPEG-LS standard
Optimized for 16-bit image data

Use Cases:

Compressing medical imaging data (DICOM)
Archiving high-fidelity scientific images
Integrating JPEG-LS support into C++ applications

Alternatives:

OpenJPEG – Focuses on JPEG 2000, which is a different standard than JPEG-LS.
libjpeg-turbo – Optimized for standard JPEG (lossy), whereas CharLS specializes in lossless.
