Optical flow estimation from image sequences has been for several years a mathematical process carried out by general purpose processors in no real time. In this work a specific a...
This paper describes a method to integrate digital topology informations in image processing libraries. This additional information allows a library user to write algorithms respe...
An algorithm for filling-in surface holes is introduced in this paper. The basic idea is to represent the surface of interest in implicit form, and fill-in the holes with a system...
