Code for generating diffused_boxes is not clear

[skbhat]

Namaste,

Thank you very much for the code. In the following line diffused boxes are created. I have two questions:

1. The lines previous to this creates many variables which are not used by the function at all. The argument gt_boxes itself is not needed.
2. I could not understand the logic behind generating boxes in this way.

        x = torch.randn(self.num_proposals, 4, device=self.device)
        x = (x * 2. - 1.) * self.scale
        x = torch.clamp(x, min=-1 * self.scale, max=self.scale)
        x = ((x / self.scale) + 1) / 2.
        diff_boxes = box_cxcywh_to_xyxy(x)
        return diff_boxes
