Abstract:

This article mainly focuses on the issue of massive image navigation. On the basis of the current technology of image pyramid, a pyramid structure with non-uniform layers and blocks is presented in this article. Then an algorithm for viewing images based on this structure is presented. It can achieve  the navigation forms of panning, zooming and the combination of both. Experimental results shows the algorithm can accomplish real-time navigation on in   finite image data. Images are displayed with the most proper resolution, and the navigation is fast and stable.

Key words: layer, block, pyramid, massive image, navigation
