Abstract: Auto recognition of aircraft in high resolution visual-band image is difficult because of clutter, shadows, self-occlusion and poor image quality. In this paper, a solution is presented based on geometric features. The image is segmented with mean shift algorithm which splits the image into some fields, and then contour of each field is traced and grouped hierarchically. According to structural features of aircraft, some geometric features are used to determine the target contour. Experimental results demonstrating the effectiveness and performance are given. It locates aircraft target with a good precision and efficiency.
