Mastering OpenCV 4 with Python

Skin segmentation in different color spaces

The aforementioned color spaces can be used in different image processing tasks and techniques. For example, the skin_segmentation.py script implements different algorithms to perform skin segmentation working in different color spaces (YCrCb, HSV, and RGB). This script also loads several test images to see how these algorithms work.

The key functions in this script are cv2.cvtColor(), which we have already mentioned on, and cv2.inRange(), which checks whether the elements contained in an array lie between the elements of two other arrays (the lower boundary array and the upper boundary array).

Therefore, we use the cv2.inRange() function to segment the colors corresponding to the skin. As you can ...
