dlib，python：如何获得整个头部（不仅是脸部）的正方形（不是矩形）？

Question

dlib.get_frontal_face_detector() returns rectangles with detected faces on photo.

And I need to get a square that covers not only face but the whole head.

Is there an easy way to do this?

Answer 1

There are 2 ways for this 1, Train your own modal and use that 2, Expand detected rectangle with some static value in % so that it covers whole head.

For example, Green is detected part and white is expanded (Photo courtesy: Google)
