Image Interpolation by Pixel-Level Data-Dependent Triangulation
We present a novel image interpolation algorithm. The algorithm can be used in arbitrary resolution enhancement, arbitrary rotation and other applications of still images in conti...

3-D reconstruction of DNA filaments from stereo cryo-electron micrographs
We propose an algorithm for the 3-D reconstruction of DNA filaments from a pair of stereo cryo-electron micrographs. The underlying principle is to specify a 3-D model of a filame...

Graph Based Image Matching
Given two or more images, we can define different but related problems on pattern matching such as image registration, pattern detection and localization, and common pattern disco...
