Abstract

This paper describes an approach to the problem of finding small-sized man-made objects in outdoor scenes, and gives some initial results of using this approach. In many military applications, the objects of interest in low-resolution imagery encompass areas covering less than 10 x 10 pixels. In such situations, there are no d.etailed geometrical features present in objects that may be used for recognizing them in a large field of view. A characteristic often used for finding small objects is the contrast between the objects and background. The contrast-based features work adequately in simple scenes with relatively clean back-ground and absence of clutter. The problem becomes much more difficult when the objects are located in outdoor scenes with real noise (bushes and other natural terrain). We believe that some gross structural properties of man-made objects, for example "blockiness" of object boundary, can serve as strong features in distinguishing them from background. clutter. Our preliminary results on this work look very encouraging and are presented. in this paper.
