Point Sampling for Point Rend #7896

Open optimaltaskin opened 2 years ago

optimaltaskin commented 2 years ago

Hello,

I want to sample uncertain points with a bias as mentioned in the paper of pointrend. Sharing relevant section from the paper as below:

bias

I have been looking for parameters to implement mildly biased point sampling but couldn't find which parameters I should change. Could you please help me to identify relevant paramters to increase bias instead of implementing a regular grid?

Thanks

I think I found which parameters I'm looking for. 

        oversample_ratio=3,   # this is k
        importance_sample_ratio=0.75   # this is beta

am I right? If so, default values are good enough :)
