J2K-Codec

The J2K-Codec refers to any codec that implements the JPEG 2000 (J2K) image compression standard. JPEG 2000 is a wavelet-based image compression standard designed to supersede the original JPEG standard. Codecs implementing J2K provide both lossy and lossless compression capabilities. The key features of JPEG 2000 codecs include superior compression performance (especially at higher compression ratios), region-of-interest coding, and progressive transmission. Unlike the Discrete Cosine Transform (DCT) used in JPEG, JPEG 2000 uses Discrete Wavelet Transform (DWT). J2K-Codecs find application in diverse fields such as digital cinema, medical imaging, archiving, and high-resolution photography, where maintaining image quality is paramount. The choice of a specific J2K-Codec depends on factors such as performance requirements, licensing considerations, and compatibility with existing software and hardware.
