How to implementation the mIoU for objects edges only.

[AkideLiu]

I would like to implement an additional evaluation hook to evaluate the performance differences for object boundaries. Could you please give me some idea of what a good starting point for implementation is?

The is an example of edge; suppose that edge detection progress could be made during run time instead modified the GT.

I suggest using laplacian kernel & theshold to filter the edge because calculating edge based on distances of each types of foreground are very time-consuming.

You could follow how STDC works and read the original paper.

These papers on calculating boundary IoU and boundary loss might be of use. @MengzhangLI any chance these could be included in the repo?

[MengzhangLI]

We do not have enough time to add boundary loss, if you are interested in it, PR is absolutely welcome!
