Motion JPEG2000 has several mechanisms that can be used to introduce a Region-of-interest (ROI) in a videostream. These methods are based on coefficient scaling, code-block selection and on tiles (using the SOP, PLT or TLM markers). We developed a proof-of-concept of interactive ROI coding within Motion JPEG2000 in order to compare these methods (both on a regular client pc as on PDA). Results show that every method has or a significant impact on the PSNR, or on the computational overhead. For real-time applications the tile-based methods perform better than the other methods, even though their visual results are less appealing.
