In mobile environments, the size of large raster images often exceeds the display area on small output devices. The rectangular FishEye-View as a Focus&Context technique can be used to provide an interactive view of the image without zooming and panning.

This paper presents the application of JPEG2000 for the demand-driven transmission of image data optimized for this display technique. The proposed method is fully compliant to the JPEG2000 standard and enhances its static concept for regions of interest to be fully dynamic. Due to limited processing power at client side almost all calculations belonging to the dynamic RoI-coding are executed at server side.
