Abstract: In the field oi image processing, target segmentation is necessary for target recognition. In some cir?cumstances, the target to be recognized is connected with other targets and their gray level is similar. Thus, it’ s difficult to separate target using a single threshold. In this paper, segmentation method for characteristic target (sphere) was analyzed, and a new method for segmentation named adaptive structuring element was introduced. This method makes up for the drawback resulted from fixed structuring element for target with different size. The trait of open operation and the method of adaptive structuring element go into particulars, and the segmen?tation of sphere target is settled in special circumstances, and it is programmed with Visual C + + 6.0. At last, segmentation results were compared in several conditions.
