`Desire Lines' are the ultimate unbiased expression of natural human purpose and refer to tracks worn across grassy spaces, where people naturally walk
For n disjoint line segments in the plane we can construct a binary encompassing tree such that every vertex is pointed, what’s more, at every segment endpoint all incident edges...

Analysis of human activity from a video camera is simplified by the knowledge of the camera’s intrinsic and extrinsic parameters. We describe a technique to estimate such param...
A robust method for the localization of frames within document images is presented. It aims at detecting regions delimited by closed polygonal lines or edges in complex color, gra...
We present a fast exact from-region visibility algorithm for 2.5D urban scenes. The algorithm uses a subdivision of line space for identifying visibility interactions in a 2D foot...
