How to train ABCNet on custom dataset with quadrilateral ground truth?

[WeitaoJ]

Hi, I want to train ABCNet on a custom dataset with quadrilateral bounding box, what should I do. Also I find the example of how to prepare custom dataset following the https://universityofadelaide.box.com/s/phqfzpvhe0obmkvn17akn9qw47u1m44i, but this code cannot handle such a dataset (horizontal or quadrilateral). Thank you!!

Hi there, you can simply interpolate the control points on the third halves of the longer side. Please refer to the figure below:

Rectangle or quadrangle can be viewed as special cases of the bezier curved bounding box.
