How to include images with no annotation in my dataset - negative samples

[tugcekeskin]

Hello,

I am trying to do Fracture/Non-fracture bone detection in my project. For Fracture case, there are 4 different classes and they have annotations (both JPG and JSON files). For Non-fracture case, there is no annonation and consists of "JPG" files. I don't know how to include Non-fracture case in my dataset and how to use it with Detectron2. I am using Faster RCNN for object detection.

I've read things about being taken as a negative sample, but I couldn't understand what exactly I should do. How will I create the dataset? I don't want to eliminate the Non-fracture case during training.

Thanks
