After modified SBR training, I get a few badcase when testing in a video. These badcases only occur in some frame. it's so weird. I have trained it with a large dataset.

Does somebody have the same issue as I describle, thanks

This does happen sometimes. I also observe this phenomenon.

KeyKy commented 4 years ago

OK，I am going to use flip augmentation. Do more experiments.

could you explain the following code in basic_batch.py?

x = x * downsample + downsample / 2.0 - 0.5
y = y * downsample + downsample / 2.0 - 0.5 # why do we need to add the offset?

Could you explain this to me? I fix the problem now and i am going to close this issue. @D-X-Y
