Paper Abstract

The accurate calculation of optical flow fields or displacement estimate fields in real-world imagery can be useful for detecting military targets. A new Kalman filter based low-level displacement estimation algorithm is derived. The gain matrix of the estimator turns out to be the Kalman gain matrix, which is dependent on the image statistics. A procedure is developed in which the gain matrix of the estimator is not chosen heuristically, but is calculated based on the statistics of the image. The optical flow fields obtained from this estimator is accurate, and is convergent faster compared to the previous pel recursive based algorithms.
