An improvement in the moment‐preserving thresholding method

Abstract Thresholding is frequently used for image segmentation. One of the most popular approach to thresholding is the moment‐preserving thresholding method proposed by Tsai in 1985. However, it does not work well when the peaks of a histogram have a great size variation. Hence, in this study we propose a simple and effective improvement in Tsai's method such that suitable thresholds can be found even when the histogram has peaks with a great size variation. Experimental results show the effectiveness of the proposed improvement. © 2008 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 18, 365–370, 2008
