OpenCV之图像像素算术操作(加减乘除)

python代码：

import cv2 as cv
import numpy as np

src1 = cv.imread("./test0.jpg")
src2 = cv.imread("./test0.jpg")
cv.imshow("input1", src1)
cv.imshow("input2", src2)
h, w, ch = src1.shape
print("h , w, ch", h, w, ch)

add_result = np.zeros(src1.shape, src1.dtype)
cv.add(src1, src2, add_result)
cv.imshow("add_result", add_result)

sub_result = np.zeros(src1.shape, src1.dtype)
cv.subtract(src1, src2, sub_result)
cv.imshow("sub_result", sub_result)

mul_result = np.zeros(src1.shape, src1.dtype)
cv.multiply(src1, src2, mul_result)
cv.imshow("mul_result", mul_result)

div_result = np.zeros(src1.shape, src1.dtype)
cv.divide(src1, src2, div_result)
cv.imshow("div_result", div_result)

cv.waitKey(0)
cv.destroyAllWindows()

C++代码：

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
