Abstract
A novel application of a phase only filter model, which is implementable in the optical domain, is proposed. In this application, automated target tracking is accomplished with a novel sub-imaging technique with correlation tracking inside a radius of interest. In this technique the image is subdivided and the correlation is tracked by comparing only the autocorrelation of the filter with itself. A radius of interest is used to reduce the number of computations required to track a moving target. Real-world video images are used to demonstrate the performance of the model.
