Handling Images without Tumors for Model Training and Testing

[zhou07]

Hi,

Great work! I have a question. Some images in my dataset do not contain tumors, so their masks are completely zero. How can prompt points be generated for these images during training and testing?

Hi,

During the training we randomly pick points from the background for these images.

For testing, we did not include such cases for calculating the metrics. But for real application, it would have some tolerance if you click a background point and no masks will be generated.
