Dear Organizer, Hello, is there a label misalignment problem on the pancreas ef8b345ea638.png in Task1? Would you please check it? Thank you

Hi pzcai,

We have thoroughly rechecked both the image and the label, and we can confirm that the label is accurate.

Hi organizer,

We also find the value problem in ef8b345ea638.png. Could you please check it again?

This label contains two numerical values: 0 and 255, but other labels are 0 and 1. What's meaning of 255 here?

Best.

Hi gepengai.ji,

Sorry for the misunderstanding. The area with non-zero pixel value indicates the positive area, while the other areas with 0 indicate the negative area. Therefore, the 255 you mentioned indicates the positive area.
