Web11 sept. 2024 · In this paper, we present a unique heuristic approach for image segmentation that automatically determines multilevel thresholds by sampling the histogram of a digital image. Our approach emphasis on selecting a valley as optimal threshold values. We demonstrated that our approach outperforms the popular Otsu's method in … Web4.4.4 Clustering (The Otsu Method) Another way of accomplishing similar results is to set the threshold so as to try to make each cluster as tight as possible, thus (hopefully!) minimizing their overlap. Obviously, we can’t change the distributions, but we can adjust where we separate them (the threshold).
