Abstract
An optical flow detection system is employed in conjunction with a target cuer system, which includes a sensor carried on a platform, for the purpose of either removing undesirable sensor motion or for the purpose of removing undesirable background motion so that targets may be more easily identified. The optical flow detection system includes an optical flow estimator which receives a plurality of pixels and generates therefrom an instantaneous pixel velocity value and a predicted pixel velocity value. The instantaneous pixel velocity values and predicted pixel velocity values are then manipulated to remove undesirable features included in the image sequence generated by the sensor. Methods for operating the optical flow detection system are also provided.
