Opencv学习笔记——图像像素算法处理

以下均为github上opencv的个人学习笔记，原路径如下：

源码示例：

import cv2 as cv
import numpy as np

src1 = cv.imread("./test0.jpg")
src2 = cv.imread("./test1.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()

1.图像的加运算

加运算就是两幅图像
