Questions on some constants #37

I have a question about why you choose: (1) 0.3&0.6 in the paper part 4.2 for pos/neg judgement (2) radius of 0.3 for proposal module (3) radius of 0.2/0.4/0.8/1.2 for set-abstraction in pointnet2backbone. And how to set them,if the size of objects from my own data is very different from that of sunrgbd?

HI @lyp0413

Those are all hyperparameters for the model. We didn't tune those numbers too much but did try a few options (like 3 options) for each of them. I think the model is not very sensitive to the (1) and (2). The (3) is in general tuned for real scale scenes with man-made objects.

If your objects are much larger/smaller than sun-rgbd objects, you should adjust (1) and (2) accordingly.
