Image Creation, Swapping, and Combining using Python

Hey Folks! Let’s do something creative. Today we are going to create an image, swap two images and combine two images, but not through photoshop or any other tool, but through Python code. So let the Fun Begin!

The above drive link contains all the images being used in the entire task. Kindly refer the link to access the images and run the code in your notebook, Have FUN!!

Steps:
import cv2

Here we import the openCV library. As computers don’t understand what images are and they only work with numbers, we create an image using numpy arrays for which we here import the library and perform necessary functions.

import numpy as np
photo_a = np.random.uniform(size=(256,256,3))*255
photo_a = np.round(photo_a)
photo_a[10:20,50:-50]= [0,0,0]
photo_a[20:200,120:-120]= [0,0,0]
photo_a[100:110,50:-50]= [0,0,0]
photo_a[190:200,50:-50]= [0,0,0]
photo_a[10:200,50:60]= [0,0,0]
photo_a[10:200,-60:-50]= [0,0,0]
photo_a[20:100,60:120] = [0,0,256]
photo_a[20:100,135:-60] = [0,256,256]
photo_a[20:100,135:-60] = [0,256,256]
photo_a[110:190,60:120] = [0,256,0]
photo_a[110:190,135:-60] = [256,0,0]
#This is our image in form of array.
photo_a

The below pic shows the image in array form

Now,we save the image over here in our folder

cv2.imwrite(“new.jpg”, photo_a)

Using necessary commands we here now display the image.

photo_a = cv2.imread(“new.jpg”)
cv2.imshow(“new pic”, photo_a)
cv2.waitKey()
cv2.destroyAllWindows()

AND

We are now going to swap images, where we will add another image in an image

Step 1:Getting the images.Trust me, it’s funny

photo1 = cv2.imread(“mona-lisa-copy_custom-cf935c261c640b9ff7e214059a0328c880c22f50-s800-c85.jpg”)
photo2 = cv2.imread(“1mj0gg.jpg”)
photo1.shape

Now,cropping the images to make sure they fit in each other, we now add the image.

photo1 = photo1[0:512,0:686]
photo2 = photo2[0:600,0:1920]
cv2.imshow(“Pic1”, photo1)
cv2.imshow(“Pic2”, photo2)
cv2.waitKey()
cv2.destroyAllWindows()

Lets swap the image

photo2[0:512,700:700+686] = photo1

Found it funny? lol

cv2.imshow(“Damn”, photo2)
cv2.waitKey()
cv2.destroyAllWindows()

NOW

We will now make a collage. As earlier said, images are only bunch of numbers to computer, so as learned in numpy, to stack images we will basically stack arrays

photo3 = cv2.imread(“modi-looking-at-shah.jpg”)
photo4 = cv2.imread(“18syng.jpg”)
photo4.shape

See images before stacking

photo3 = photo3[0:400,0:700]
cv2.imshow(“pic1”, photo3)
cv2.imshow(“pic2”, photo4)
cv2.waitKey()
cv2.destroyAllWindows()

See images after stacking

photo5 = np.hstack((photo3,photo4))
cv2.imshow(“Damn”, photo5)
cv2.waitKey()
cv2.destroyAllWindows()

ANDDD…The task is completed!

Thank You..!! Will be back with more fun.
