소스

import numpy as np
import cv2 as cv

img = cv.imread("threshold.png", 0)

res, thresh1 = cv.threshold(img, 127, 255, cv.THRESH_BINARY)
res, thresh2 = cv.threshold(img, 127, 255, cv.THRESH_BINARY_INV)
res, thresh3 = cv.threshold(img, 127, 255, cv.THRESH_TRUNC)
res, thresh4 = cv.threshold(img, 127, 255, cv.THRESH_TOZERO)
res, thresh5 = cv.threshold(img, 127, 255, cv.THRESH_TOZERO_INV)

titles = ['Original Image','BINARY','BINARY_INV','TRUNC','TOZERO','TOZERO_INV']
images = [img, thresh1, thresh2, thresh3, thresh4, thresh5]

for i in range(6):
    cv.imshow(titles[i], images[i])
cv.waitKey(0)
cv.destroyAllWindows()
