I’m training a faster RCNN to detected object wich appear sometime in my scene, the detection works well but when the object doesn’t appear, I have a lot of false detection with high accuracy.
So my idea was to add images without object to detect (empty label file), so the faster RCNN learn the empty scene.
But when i’m training the following message is displayed:
1218/1334 [==========================>...] - ETA: 1:36 - rpn_cls: 0.0456 - rpn_regr: 0.0236 - detector_cls: 0.1179 - detector_regr: 0.1013 No GT bboxes found in my_image.png
Is it only a warning or is the image without ground true boxes is ignored so it’s useless to add images like this one?
