2017-11-02 06:53:22 -0600	marked best answer	Face detection bounding box Hi I was wondering how the size of the bounding box around a detected face is determined. Is it the smallest box that satisfies the detection? Sometimes the boxes cover the whole face, but sometimes not. I appreciate that the box has to be a square of a size between `minSize` and `maxSize`. How does the algorithm create the bounding box edges? Thanks
