Özet

In this paper, a new dichotomization technique is proposed for multilevel thresholding. The proposed method is based on selection of the consistent peak location of the correlation function as threshold value over the interested histogram region. Different dichotomization processes are also adapted to the multilevel thresholding proposed by Yen et al. (Yen, J.C., Chang, F.J., Chang, S., 1995. IEEE Trans. Image Process. 4 (3), 370-378). Finally an evaluation is performed for different dichotomization processes and a comparative study is performed over the set of some real images for different methods. It is observed that the proposed method gives consistent results in the sense of human perception and gives satisfactory results to find uniform regions in the image plane.
