基于opencv的图像自适应处理

import cv2
image = cv2.imread(rE:OpenCVPython OpenCV codePython OpenCVslhuan1.jpg)
image = cv2.resize(image,None, fx=1/2,fy=1/2)
image_gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
t1, dst1 = cv2.threshold(image_gray, 127, 255, cv2.THRESH_BINARY)
# dst1 = cv2.resize(dst1, None, fx=3/, fy=1/2)
t2, dst2 = cv2.threshold(image_gray, 127, 255, cv2.THRESH_BINARY_INV)
# dst2 = cv2.resize(dst2, None, fx=1/4, fy=1/2)
t3, dst3 = cv2.threshold(image_gray, 127, 255, cv2.THRESH_TOZERO)
# dst3 = cv2.resize(dst3, None, fx=1/2, fy=1/2)
t4, dst4 = cv2.threshold(image_gray, 127, 255, cv2.THRESH_TOZERO_INV)
# dst4 = cv2.resize(dst4, None, fx=1/2, fy=1/2)
t5, dst5 = cv2.threshold(image_gray, 127, 255, cv2.THRESH_TRUNC)
dst5 = cv2.resize(dst5, None, fx=1/2, fy=1/2)
cv2.imwrite(./01.jpg, dst1)
cv2.imwrite(./02.jpg, dst2)
cv2.imwrite(./03.jpg, dst3)
cv2.imwrite(./04.jpg, dst4)
cv2.imwrite(./05.jpg, dst5)

cv2.imshow(BINARY, dst1)
cv2.imshow(BINARY_INV, dst2)
cv2.imshow(TOZERO, dst3)
cv2.imshow(TOZERO_INV, dst4)
cv2.imshow(TRUNC, dst5)
cv2.waitKey()
cv2.destroyAllWindows()

只需更改路径就可获得你需要的图片，路径一定要是英文的。
