Abstract: The first step in image analysis is segment the image. Segmentation subdivides an image into its constituent regions or objects. Among all Segmentation Techniques, the Thresholding methods are widely used because of their advantages of simple implement and time saving. Thresholding method is based on a threshold value. The key of this method is to select the threshold value. An Otsu method is one of the superior threshold selection methods. Image segmentation based on Otsu’s method and modified Otsu algorithms are thoroughly presented in the paper. 
Keywords: Image segmentation, Threshold selection, Histogram, Otsu’s method.
