This paper presents a survey of the characteristics of a vision system implemented in a reconfigurable/programmable chip (FPGA). System limitations and performance have been evaluated in order to derive specifications and constraints for further vision system synthesis. The system hereby reported has a conventional architecture. It consists in a central(More)
During circumferential pulmonary vein isolation, radiofrequency lesions are created in the transition zone between the left atrium and the pulmonary veins, outside the ostia, to avoid stenosis. Three-dimensional impedance maps were constructed for 25 patients with paroxysmal atrial fibrillation. In the first 15 patients, impedance was measured inside the(More)
 High-speed imagers are required for industrial applications, traffic monitoring, robotics and unmanned vehicles, movie-making, etc. Many of these applications call also for large spatial resolution, high sensitivity and the ability to detect images with large intra-frame dynamic range. This paper reports a CIS intelligent digital image sensor with(More)
