Otsu Method is one of the most powerful global thresholding method for the image segmentation.But it gives only one threshold which is useful to study only two regions in the segmented image and it is preferred to be applied on the image having bimodal histogram.But recursive algorithm of the same can be applied on the image having multimodal histogram and also gives more than one threshold which is useful to study two different regions at each threshold and we can also study more than two regions simultaneously in the segmented image by applying all the thresholds obtained by the recursive algorithm simultaneously.
