Small objects segmentation isn't possible #6435

Open Samyk01 opened 1 year ago

Samyk01 commented 1 year ago

When drawing polygons the lowest size it can go is 3x3 pixels, i need to segment details that are sometimes 2x1 pixels, is it not possible on cvat to do so ?

Hi, could you please describe the use case? I'm not sure segmentation models can work with pixel precision.

It's for lesion segmentation on medical images. Some lesions are quite small, when i draw a polygon around them and press N the polygon just disappears, i need to make the shape bigger for it to stay.

As a workaround you can try using points. Probably this restriction can be redesigned.
