Webthat maximize the between-class variances of the histogram. Therefore, Otsu method is optimal for thresholding a histogram with distinct bimodal or multimodal distribution. However, in general, real world images rarely pos-sess such characteristics. It has been shown that Otsu method biases toward the component - with larger within class ... WebJan 8, 2013 · The threshold value can be chosen arbitrary. The algorithm then finds the optimal threshold value which is returned as the first output. Check out the example below. The input image is a noisy image. In the first case, global thresholding with a value of 127 is applied. In the second case, Otsu's thresholding is applied directly.

WebJan 29, 2024 · Otsu threshold, also known as the maximum variance threshold, was proposed by Otsu zhanzhi of Japan in 1979. It is derived based on the principle of discrimination and least square method. Its basic idea is to maximize the variance between classes, so as to obtain the optimal threshold.
