Perceptual Grouping for Contour Extraction
This paper describes an algorithm that efficiently groups line segments into perceptually salient contours in complex images. A measure of affinity between pairs of lines is used ...

Size space tradeoffs for resolution
We investigate tradeoffs of various basic complexity measures such as size, space and width. We show examples of formulas that have optimal proofs with respect to any one of these...

FOGGER: an algorithm for graph generator discovery
To our best knowledge, all existing graph pattern mining algorithms can only mine either closed, maximal or the complete set of frequent subgraphs instead of graph generators whic...

Optimizing Algorithms for Region-of-Interest Video Compression, with Application to Mobile Telehealth
Wireless communication of video poses constraints on information capacity. Region-of-Interest (ROI) video coding provides higher quality in the ROI, but poorer quality in the back...
