question about the calculation in cs_fddb_convert_to_darknet.py about fddb

This might be very late but just answering it for fun 😆

I was wondering what unit of measure you use in the file for calculating the bounding box? The values are all less than 0.

FDDB has ellipse as ground truth. Now to convert it to rectangular bounding box, the code converts it approximate box which is supposed to have a max IOU w.r.t the original ellipse that is done by the formula

Can I also calculate the values for x, y, length and width of the bounding box in integer pixel values?

FDDB/scripts/cs_fddb_convert_to_darknet.py

Lines 66 to 69 in 8fd5ca2

	bbox_x = center_x / img_width
	bbox_y = center_y / img_height
	bbox_w = (2 * calc_x) / img_width
	bbox_h = (2 * calc_y) / img_height

Removing the divisions here will get you the original pixel value
