Abstract
Edge definition in FLIR images is improved by assigning to each pixel (X) the average intensity value of that 3.times.3 pixel sub-matrix (30a-30i) containing the pixel (X) which exhibits the smallest edge value. Apparatus for obtaining that intensity value in real time is disclosed. This process can be iteratively repeated on the same image, with each iteration creating more enhanced edges and greater area smoothing between edges.
