JPEG 2000
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method.
Main usage
JPEG 2000 is commonly used for digital cinema and digital television production, medical imaging, and for the archival and storage of digital photographic images.
- Lossless and lossy compression
- High compression ratios
- High image quality
- Support for transparency and alpha channels
- Support for multiple resolutions
