Split and Merge Image Color Space Channels in OpenCV and NumPy
Introduction
In this tutorial, we will show you how to split the image into it’s multiple channels by using the OpenCV cv2.split() function and also with Numpy. We will also show you how we can merge the single channel images to generate the multi-channel image with the cv2.merge() function.
Color Spaces and Channels
The colors of images can be organized in many ways and this scheme is known as color space. For example, a popular way of representing the image is
