Motion JPEG2000 Interactive Region-of-interest coding on mobile devices Host Publication: Finds and Results from the Swedish Cyprus Expedition: A Gender Perspective at the Medelhavsmuseet Authors: G. Van Wallendael, S. Lievens, T. Dams and P. Schelkens Publication Date: Mar. 2007
Abstract: 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.
