Hands-On Image Processing with Python

Simple image morphing - α-blending of two images using cross-dissolving

The following code block shows how to start from one face image (image₁ being the face of Messi) and end up with another image (image₂ being the face of Ronaldo) by using a linear combination of the two image numpy ndarrays given with the following equation:

 

We do this by iteratively increasing α from 0 to 1:

im1 = mpimg.imread("../images/messi.jpg") / 255 # scale RGB values in [0,1]im2 = mpimg.imread("../images/ronaldo.jpg") / 255i = 1plt.figure(figsize=(18,15))for alpha in np.linspace(0,1,20): plt.subplot(4,5,i) plt.imshow((1-alpha)*im1 + alpha*im2) plt.axis('off') ...
