otsu阈值分割算法python

OTSU阈值分割算法是一种对图像进行二值化的高效算法，由日本学者OTSU于1979年提出。在OpenCV中，可以使用Python来实现OTSU阈值分割算法。以下是一个示例的Python代码：

import cv2
import numpy as np
from matplotlib import pyplot as plt

image = cv2.imread("E:/python/cv/OTSU/test.jpg")
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

ret1, th1 = cv2.threshold(gray, 0, 255, cv2.THRESH_OTSU)

plt.subplot(131), plt.imshow(image, "gray")
plt.title("source image"), plt.xticks([]), plt.yticks([])

plt.subplot(132), plt.hist(image.ravel(), 256)
plt.title("Histogram"), plt.xticks([]), plt.yticks([])

plt.subplot(133), plt.imshow(th1, "gray")
plt.title("OTSU,
