The rectangular fish eye view as an efficient method for the transmission and display of large images
Uwe Rauschenbach · 2003
With the advances of mobile computing technology, the users of mobile hardware expect the same service as users of stationary computers do. Access to large images over the Internet poses two problems to users of wireless data communication devices and mobile computers: low transmission bandwidth and small screen space. In this paper, an integrated image transmission and display method is proposed, which efficiently uses both transmission bandwidth and screen real estate. In order to achieve that, we developed a level-of-detail and region-of-interest transmission scheme for raster images based on embedded zerotree wavelet coding. A special fish eye view technique is built on that transmission scheme, which can benefit directly from the properties of a modified wavelet decomposition.
