Automatic segmentation method for IR target image

For the segmentation of moving targets in the IR imaging guidance system, a new automatic segmentation method is presented. First, the IR image is filtered by multiscale morphological filters, suppressing the background and eliminating the clusters to enhance the contrast between the object and background. Secondly, the joint relative entropy threshold is applied to get the thresholded image; Finally, the thresholded image is filtered by morphological filter again. The experimental results verify the effectives and robustness of this segmentation method which can facilitate the target recognition and tracking in the next step.
