Image compression to enhance optical correlation
First Claim
1. A method, comprising:
- receiving a reference image having a reference feature and a comparison image having a comparison feature;
compressing the reference image and the comparison image with a substantially linear phase, symmetrical coding to generate coefficients for the images, wherein a difference between the coefficients is substantially similar to a difference between the reference feature and the comparison feature; and
displaying the coefficients as coherent images at an input plane for optical correlation.

Abstract
The present invention is in the area of optical correlation. Embodiments of the invention encompass systems of process and/or equipment to compress images for optical correlation. Further embodiments of the invention may compress images to correlate objects and gridlock sensors with images based upon track data from sensors. In many of the embodiments of the invention, the sensors may comprise radars, global positioning systems, laser target designators, seismic sensors or systems of seismic sensors comprising hydrophones and geophones, and other similar systems. While some embodiments of the invention may comprise an optical correlator, many embodiments of the invention perform one or more analyses statistically. In addition, many embodiments of the invention comprise software that can execute on a laptop, desktop, or similar computer.
