Let's analyze the performance of the fast sorting method. The time performance of fast sorting depends on the depth of the fast sort recursion, and recursive tree can be used to describe the execution of the recursive algorithm. As shown in Figure 9‐

Now there's a need to collect faces, and there's only one person in each picture. My solution is to use a collection to record a video and upload it to the PC. Use OpenCV on your PC to save each frame in the picture as a JPG image. Here's the code:
