Detecting circles from a digital image is very important in shape recognition. In this paper, an efficient randomized algorithm (RCD) for detecting circles is presented, which is not based on the Hough transform (HT). Instead of using an accumulator for saving the information of the related...
In recent years, the field of active contour-based image segmentation has seen the emergence of two competing approaches. The first and oldest approach represents active contours in an explicit (or parametric) manner corresponding to the Lagrangian formulation. The second approach represents...
A novel technique for multiscale curvature computation on a smoothed 3-D surface is presented. This is achieved by iteratively convolving local parameterizations of the surface with 2-D Gaussian filters. In our technique, semigeodesic coordinates are constructed at each vertex of the mesh which...
An important issue in the realization of an autonomous robot with stereoscopic vision is the control of vergence. Together with version, it determines uniquely the position of the fixation point in space. Vergence control is directly related to both depth perception and binocular fusion ....
