Abstract

Imagery must be adequately processed and adapted to be used in mobile environments. This contribution shows that this can be reached by a rigorous combination of all stages of the image communication pipeline to the task at hand. To achieve this, the modern imaging standard JPEG2000 serves as a foundation for compression and streaming. Based on the concept of regions of interest (ROI) and levels of detail (LOD), powerful generic strategies for content handling are proposed. The task is represented by one of three common problems in mobile environments—image browsing, viewer guidance, and content exchange. Besides new ideas to accomplish these tasks on application level, appropriate strategies to combine the respective visual representation with compression and streaming are introduced. In addition to a much better content representation, the achieved results show that the consumed resources can be strongly decreased by the proposed new concepts for mobile image communication using JPEG2000.
