Matterport Mask RCNN TRAIN_ROI_PER_IMAGE explanation?
<p>I have been trying to train a breast cancer segmentation model with mask rcnn. I have been able to understand almost all the hyperparameter but this one variable <code>TRAIN_ROI_PER_IMAGE</code> I just can't seem to wrap my head around it and there's little to no documentation available for it.
If anyone could please explain it to me, it would be super helpful for my research.</p>
