In slap fingerprint segmentation, crease is the most difficult edge to correctly detect. In this paper, we present a novel yet simple and accurate algorithm for the principal axis and crease detection. Firstly, the principal axis of each foreground region is detected using the minimal rotational inertia; Secondly, the crease detection is done based on cost function minimization. This algorithm has...
A novel convenient method for hand-eye robot system calibration that includes camera calibration and hand-eye calibration is presented. In the classical robot vision system calibration, the camera calibration and the hand-eye calibration are completed separately. In this paper, we propose a joint camera calibration that integrate the camera calibration and the hand-eye calibration simultaneously....
