Performances of image motion tracking with optical correlation
The paper tackles the problem of real-time image motion tracking as a baseline function for visual motion estimation. Motion tracking is performed using the principles of 2D area correlation and joint transform correlation. To cope with real-time requirements a compact embedded optical Joint Transform Correlator design is presented, which allows using image motion tracking in mobile application...
متن کاملSpacecraft Navigation Using a Grayscale Optical Correlator
In this paper, recent technical progress in developing a compact high-speed Grayscale Optical Correlator (GOC) for real-time pattern recognition at the Jet Propulsion Laboratory (JPL) will be presented. This GOC, under partial sponsorship by the Telecommunication and Mission Operation Directorate (TMOD) program at JPL, is being investigated for spacecraft navigation applications. All up-to-date...
متن کاملComparison of Temporal Filters for Optical Flow Estimation in Continuous Mobile Robot Navigation
We present our complete study involving comparisons of three spatio-temporal filters used in the estimation of optical flow for continuous mobile robot navigation. Previous comparisons of optical flow and associated techniques have compared performance in terms of accuracy and/or efficiency, and only in isolation. These comparisons are inadequate for addressing applicability to continuous, real...
متن کاملDual Optic-flow Integrated Inertial Navigation
This paper addresses the recent development of real-time visual odometry system based on dual optical-flow systems and its integration to aided inertial navigation aiming for small-scale flying robots. To overcome the unknown depth information in optic-flows, a dual optic-flow system is developed. The flow measurements are then fused with a low-cost inertial sensor using an extended Kalman filt...
متن کاملOptical snake-based segmentation processor with a shadow-casting incoherent correlator.
What is believed to be the first incoherent snake-based optoelectronic processor that is able to segment an object in a real image is described. The process, based on active contours (snakes), consists of correlating adaptive binary references with the scene image. The proposed optical implementation of algorithms that are already operational numerically opens attractive possibilities for faste...
