@yanni1995 add images without labels to your dataset. These will be used as background images automatically.

need an empty txt file or no txt file

[glenn-jocher]

no txt file required for background images.

[yanni1995]

ok,thanks you answer

[frabob2017]

I did the exact same things. 90% of my dataset are background images without labels. It looks that too many background images will decrease detection sensitivity based on my preliminary observation. I am still working on it.

Do we need to add a name/label in the config/YAML file?

E.g.,:

names:
  0: cats
  1: dogs
  2: mice
  3: background

[glenn-jocher]

@Rich2020 no, you just add any background images you want to your dataset by placing them in the same directory as your training images. You'll see the extra images shown in the train/val set stats when training starts. No other changes necessary.

@glenn-jocher Brilliant. Thank you and happy holidays!
