Order matrix not correct even after adjusting 'th' and 'dilate_kernel'

[jiunyen-ching]

Hi, I was testing out the demo codes on this RGB image

and its instance mask

I slowly increased the 'th' and 'dilate_kernel' from (0.1, 5), (0.3, 7), (0.5, 9), (0.7, 11) respectively as advised in #14 but the order matrix is still not correct.

From the order matrix, Instance 3 (table) is not considered as an occluder to Instance 5 (bench). May I ask for some advice as to how to improve the situation?

Why are there margins between objects in the segmentation map? These may severely affect the results. Dilation process can mitigate it but not thoroughly . You might have to deal with the margins before testing it.

Unfortunately the margins are due to the NYU annotations. I will dilate the masks and try to infer their order again. Will update here if it works

The masks not tightly fitting each other is indeed quite troublesome to handle. Only certain cases where the masks are tightly fitting, it works well.
