Potential improvement in nodule detection #35

Open totesarana opened 7 years ago

totesarana commented 7 years ago

Hi lfz,

I have observed one thing during playing with your detector. Looks like your detector performs much better on CTs with smaller slice thickness (i.e., higher resolution on z axis). This is significant as I observed ~500 proposals (before iou step) for higher resolution CTs and around ~2000 ~ 3000 proposals for lower resolution CTs. Do you think it could be beneficial to train two detectors for these two types of CTs?

Thank you for letting me know that, I think firstly any method would perform better with smaller slice thickness because of more information.

but this difference is too big? so maybe you can try that idea. I think it might work
