Motion JPEG2000 interactive Region-Of-Interest coding on mobile devices

This paper discusses the latest ISO/ITU-T still image coding standard, JPEG2000 and the moving pictures variant, Motion JPEG2000. These offer greater functionality and compression performance compared to their predecessors, JPEG and Motion JPEG, which are heavily used on the Internet and in digital cameras. We developed a proof-of-concept of interactive Region-Of-Interest coding within Motion JPEG2000. For this we used several ROI coding techniques, namely coefficient scaling, code-block selection and tiling and a specially developed client/server architecture. Our main observation was the impact on required bandwidth and computing resources. Potential applications of interactive Region-Of-Interest coding reside in medical imaging, telemedicine networks, surveillance video and many more.
