Color Spaces
Explore various color spaces like BGR, grayscale, HSV, Lab, and RGB and learn how to convert images among them using OpenCV's cvtColor function in C++. This lesson helps you understand how color represents pixel data and how to manipulate it for image processing.
What is a color space?
A color space is a specific organization of colors. It’s essentially a system of representing an array of pixel colors. There are several color spaces, such as BGR, grayscale, HSV, Lab, and many more. Here, we’ll learn to convert our image from one color space to another.
Converting from BGR to grayscale
OpenCV reads images in BGR format. To ...
