A recent and fascinating interest in computational symmetry for computer vision and computer graphics applications has led to a remarkable realization of new symmetry detection algorithms. Such a concern is culminated in a symmetry detection competition as a workshop affiliated with the 2011 and 2013 CVPR Conferences. In this paper, we propose a method based on the computation of the symmetry level...
Medical image processing fuses the image processing technologies in the medical disciplines. Particularly, computed tomography images provide a 3D vision of any part of the human body. These 3D images are generated by CT-Scanner devices. In this paper, we propose an advanced method of CT-Scanner identification from its 3D images. Basically, we analyze the sensor noise in order to identify the source...
General object recognition is difficult. We had proposed a novel solution for object recognition in an unconstrained environment using a tag (Matas[2]). This simplifies the problem by placing tags of special pattern on the objects that allows us to determine the pose easily. A robust calibration chart detector was developed for the first stage of the solution (Soh[l]). This paper investigates the...
High resolution ToF measurements from multiple ultrasonic transmitter/receiver pairs allow determination of distance and bearing of reflectors. By combining methods for solving the echo correspondence problem, in case of multiple reflectors, and avoiding outliers, typically occurring on object discontinuities, a high quality map of 3D reflection points is obtained. This information is suitable for...
