Create Empty Json with Labelme

Question

Here is an example Labelme window, with 5 polygon labels marked (want to detect some old video tapes). And yes i can easily save its json file

But there are some images, with out any labels (which are not video tapes). Such as this image below:

I want to save this last image to the database too, which could help to train better and more robust detection algorithm. But i can't save it's json file, since there aren't any polygons drawn on this.

Is it possible to create these kind of unmarked images' json files?

glenn-jocher's answer: "to use background images in training you simply add these images to your dataset. No labels are required for background images."

in short, just add the labelless images without json files
