About loading the labels

Why you do this one in the datasets.py?
x1 = w * (labels[:, 1] - labels[:, 3]/2)
y1 = h * (labels[:, 2] - labels[:, 4]/2)
x2 = w * (labels[:, 1] + labels[:, 3]/2)
y2 = h * (labels[:, 2] + labels[:, 4]/2)
# Adjust for added padding
x1 += pad[1][0]
y1 += pad[0][0]
x2 += pad[1][0]
y2 += pad[0][0]
# Calculate ratios from coordinates
#print labels,float(h) / float(padded_h), h, padded_h, w, padded_w
