Abstract

Due to resource limitations, the handling of large imagery in mobile environments is still problematic. This applies especially for browsing and navigation tasks. As existing technology fails to adapt to restrictions, new ideas for appropriate image handling are required. This publication proposes a new approach for image browsing based on JPEG2000, blurring, and progressive refinement. Blurring is an effective means for user guidance and thus is selected and combined with progression to increase usability aspects during browsing. The resource-saving implementation of the user interface is founded on the image compression standard JPEG2000. The DiscreteWavelet Transform and options for Random Spatial Access are the main features we take advantage of in order to extract the user interface directly from the encoded image data. A discussion of the results shows that this approach saves valuable computing power and bandwidth compared to traditional technology, and is an appropriate means to support browsing of large imagery on mobile devices.
