OpenJPEG is an open-source JPEG 2000 codec written in C language. For now, JPEG 2000 is a file format hanging by a thread, but who knows, maybe a future imaging revolution will change that idea. 0000001060 00000 n For lossy compression, data has shown that JPEG 2000 can typically compress images from 20%-200% more than JPEG. 86th Meeting – Sydney, Australia - JPEG Committee releases a call for evidence for image compression based on AI. Together, these abilities created a much better alternative than the original JPEG solution.So, the question remains: why does no one seem to use JPEG 2000?
