Some questions about your dataset. about vps HOT 2 CLOSED

Hi, @Moqixis

Q1. Are there only frames containing polyps in your videos in the positive part? And how do you use the non-polyp frames in your train and test dataset?
A1. In our journal version, we only consider the situation of assuming at least a polyp exists in a frame. So we do not include negative sample in our training pipeline. We plan to use both of them in the near future.

Q2. How do you deal with the non-polyp frames when you calculate evaluation such as Dice and so on?
A2. Nice question. To my best known, existing metrics can not well evaluate the real performance for those non-polyp frames.
