Object Recognition by Matching Symbolic Edge Graphs
We present an object recognition system based on symbolic graphs with object corners as vertices and outlines as edges. Corners are determined in a robust way by a multiscale combi...

A Comparison of Navigation Techniques Across Different Types of Off-Screen Navigation Tasks
In many systems such as PDAs, users access data through a limited viewport. This means that users have to frequently navigate to regions that are off-screen to view important conte...
