Mastering OpenCV 4 with Python

Concepts of pixels, colors, channels, images, and color spaces

There are several different color models, but the most common one is the Red, Green, Blue (RGB) model, which will be used to explain some key concepts concerning digital images.

In Chapter 5, Image Processing Techniques, the main color models (also known as color spaces) will be fully explained.

The RGB model is an additive color model in which the primary colors (R, G, B) are mixed together to reproduce a broad range of colors. As we previously stated, in the RGB model, the primary colors are red, green, and blue.

Each primary color, (R, G, B), is usually called a channel, which is commonly represented as an integer value in the [0, 255] range. Therefore, each channel produces ...
