Abstract

Detection of infrared dim small target is an important task in many application fields such as automatic target detection, target search and tracking, and early warning. By combining the block-based background reconstruction and min-cut of non-balanced graph, a dim small target detection algorithm is presented. First, a background reconstruction based on a new modeling is presented. Secondly, the background is suppressed though subtracting the reconstructed image from the original image. Lastly, further segmentation using min-cut for non-balanced graph to the background suppressed image is proposed in order to obtain the binary image containing target. The optimal segmentation threshold is selected by heuristic search based on the optimal min-cut. Experimental results show that the proposed method can suppress background noise and clutter effectively and detect infrared small target accurately.
