Clutter rejection for FLIR target detection system

摘要

The method of clutter rejection in digitised images, involves locating the centroid pixel of a potential target object in an image, and establishing around the centroid pixel at least one closed path of pixels. The intensity of the individual pixels of the path are compared to the intensity of the centroid pixel. An identification of the potential target object is provided as true if all of the individual pixels have a predetermined intensity relation to the centroid pixel. A number of nested paths of pixels are established around the centroid pixel, and the potential target object is identified as true if all pixels of any path have the predetermined intensity relationship to the centroid pixel. The path pixels are compared to the centroid pixel one path at a time, working outward from the innermost of the nested paths.
