3 Ways of Image Addition in Python with NumPy, OpenCV and Pillow Libraries
Introduction
Addition of images might sound weird but people forget that an image is essentially a collection of numeric pixels. So we can do pixel-wise addition of the two images resulting in a new image. In this article, we will see multiple ways we can perform the addition of images in Python by using NumPy, OpenCV, and PIL libraries.
Addition of Images
When we add two images it does pixel-wise addition where each pixel in one image is added to the corresponding pixel of the other image, resulting in a new third image.
Mathematically, when we add two images A and B the pixel-wise operations to get new image C can be done as follows –
C(x,y) = A(x,y) + B(x,y)
Where,
- A(x,y) denotes the
