How to Adding and Blending image in OpenCV. 

import cv2
import numpy as np

img = cv2.imread('Mehjabin.png')
img2 = cv2.imread('ImageCV.jpg')

resize_img = cv2.resize(img2, (img.shape[1], img.shape[0]))

add_img = cv2.add(img, resize_img)

Blending_img = cv2.addWeighted(img, 0.6, resize_img, 0.4, 0)

while True:
    cv2.imshow('window', img)
    cv2.imshow('window2', img2)
    cv2.imshow('window3', Blending_img)
    if cv2.waitKey(1) == 27:
        breakcv2.destroyAllWindows()
