Otsu threshold binarization image. To write your own work. Otsu method from Japan Otsu, scholars put forward in 1979, is an Adaptive threshold method, also known as Otsu method, referred to as OTSU. It is based on the Gamma characteristic of the image, image into the background and objectives part 2. Background and goals between the larger the variance between means the difference between the 2 parts of the image larger, when part of the goal is divided into background or background is wrong is divided into objectives will lead to smaller differences in part 2. Therefore, the variance between the biggest split means minimum misclassification probabilities.
