Implementation of QUAD part of the paper

[Adnan-annan]

How do you modify the geometry map generation for QUAD part of the paper? what does it mean by the statement "For the QUAD ground truth, the value of each pixel with positive score in the 8-channel geometry map is its coordinate shift from the 4 vertices of the quadrangle" I would like to know all the modification needed to be made in the code for implementing for QUAD part. How to modify the geometry map generation for QUAD method ? @songdejia
