A question on generateBoundingBox() function for generating the bounding boxes from the heatmaps

[qiongcao]

Hi ya,

At test, given an image, the PNet outputs the heatmaps of classification scores (i.e. HW2) and the offsets
(i.e. HW4) for each position. Then the python function generate_bbox is used to produce the bounding box for the image. I was confused how this generate_bbox works. What's the meaning of the offsets (i.e. HW4) for each position.

Many thanks
