Abstract

This paper present a method for the extraction and segmentation of small targets in image sequence captured in static explosion test, whose background is complex with numerous interference. Three frames difference method is adopted to process the original image sequence to obtain the foreground image. Since the foreground image is heavily contaminated by noise, so the gray square enhancement method is used to increase the contrast between the noise and the target. The modified Otsu method is employed to obtain the global optimum threshold, and the segmentation of the foreground image is accomplished. Finally, morphological processing is performed, and the noise of the isolated points is eliminated, and the weakening of the target in the process of differential and segmentation is resumed. Through a series of processing, the extraction of fragments in static explosion test image sequence is completed, and the trajectories of the fragments are obtained.
