Modeling and recognition of 3D objects by surface is an important problem in machine vision. Given a large number of range data points of an object surface, we present a relaxatio...

In this paper, we describe a commercial vision system for the digitisation and extraction of horizons drawn with coloured pencils on seismic sections. The system combines image pr...
The photometric sampling method [4] extracts shape and reflectance properties of surfaces (Lambertian,specular,and hybrid)by using multipleillunrinationdirectionsand asingle viewi...
We describe a method based on the Hough transform to compute a set of parameters that completely describe line segments. By complete, we mean the description includes the endpoint...
A schcmc of camera calibration is proposed. The focal length and the orientations of the scenc coordinatc axes are computcd by dctecting the vanishing points of two sets of lincs ...
There is a tradeoff between noise insensitivity and accurate position in edge detection. This paper suggests an adaptivealgorithm which takes advantage of both LOG and NonLL filte...
