Addition and Blending of images using OpenCv in Python
We know that when we solve any image related problem, we have to take a matrix. The matrix content will vary depending upon the image type - either it would be a binary image(0, 1), gray scale image(0-255) or RGB image(255 255 255). So if we want to add of two images then that means very simple we have to add respective two matrices.
In OpenCV library, we have a function cv2.add() to add the images. But for image addition the size of the two images should be same.
Addition of two images
import cv2 # Readingour Image1 my_firstpic = cv2.imread('C:/Users/TP/Pictures/west bengal/bishnupur/mqdefaultILPT6GSR.jpg', 1) cv2.imshow('image', my_firstpic) # Readingour Image2 my_secpic = cv2.imread('C:/Users/Satyajit/Pictures/west bengal/bishnupur/pp.jpg', 1) img = cv2.add(my_firstpic,my_secpic) cv2.waitKey(0) cv2.distroyAllWindows()
Output
Blending of two images
cv2.addWeighted() function is used for blending of two images.
Example code
import cv2 # Read our Image1 My_first = cv2.imread('C:/Users/TP/Pictures/west bengal/bishnupur/mqdefaultILPT6GSR.jpg', 1) # Reading ourImage2 My_second = cv2.imread('C:/Users/TP/Pictures/west bengal/bishnupur/pp.jpg', 1) # Blending the images with 0.3 and 0.7 My_img = cv2.addWeighted(My_first, 0.3, My_second, 0.7, 0) # Show the image cv2.imshow('image', My_img) # Wait for a key cv2.waitKey(0) # Destroy all the window open cv2.distroyAllWindows()
