What is JPEG 2000?
JPEG 2000 is an image compression standard based on wavelet technology, offering both lossy and lossless compression. It provides better compression than traditional JPEG, especially at low bit rates, and supports features like progressive decoding, region-of-interest coding, and transparency. JPEG 2000 is used in professional applications like digital cinema (DCI), medical imaging, and satellite imagery.
