This paper presents two new methods for detecting edges in millimeter-wave radar images. The first method is based on a deformable template model of edge shapes and a random field model of the millimeter-wave imaging process. The second method is similar to the first, except that the imaging model component is replaced by one that is based on the magnitude and direction of the image gradient. Experimental results are shown to illustrate the advantages of using these methods over traditional edge detectors.
