Train neural network on a single image set?

I'm trying to set up a neural network to recognise a specific object in images. Is it possible to train it on only images of the target item, or does the network require images which do not contain it to contrast with (which seems to be the case)?

If you do not train with alternative inputs you will probably have too many false positives.

Hope this helps
