Hi,
I’ve been using Mask R-CNN on my project and I’m very happy with the detection results. However, I’m not fully satisfied by the segmentation as I don’t think it is precise enough for my needs.
I tried to modify the MaskRCNNPredictor without success. So:

What can I do to improve the segmentation part?
Can I change the loss?
Can I modify other parts of the model?

Thank you for your help
