OpenCV之图像像素操作(逻辑操作)

Posted 2021-08-13 MachineLP

python代码：

import cv2 as cv
import numpy as np

# create image one
src1 = np.zeros(shape=[400, 400, 3], dtype=np.uint8)
src1[100:200, 100:200, 1] = 255
src1[100:200, 100:200, 2] = 255
cv.imshow("input1", src1)
# create image two
src2 = np.zeros(shape=[400, 400, 3], dtype=np.uint8)
src2[150:250, 150:250, 2] = 255
cv.imshow("input2", src2)

dst1 = cv.bitwise_and(src1, src2)
dst2 = cv.bitwise_xor(src1, src2)
dst3 = cv.bitwise_or(src1, src2)


cv.imshow("dst1", dst1)
cv.imshow("dst2", dst2)
cv.imshow("dst3", dst3)

src = cv.imread("./test.png")
cv.namedWindow("input", cv.WINDOW_AUTOSIZE)
cv.imshow("input", src)
dst = cv.bitwise_not(src)
cv.imshow("dst", dst)

cv.waitKey(0)
cv.destroyAllWindows()
