is it possible to match an image from an external source?

[avnerbarr]

I've trained my dataset withe my set of images. I was wondering if it is possible to find a match using an external image from a picture I've taken with a phone camera

Yes, you can use search.lua in /src/torch/11-similarity-searcher-cnn-file like this
$luajit search.lua test.jpg /home/.../A -dataFolder /home/.../B
A is the folder where test.jpg is located in; B is the dataset of images to be compared, -dataFolder option is added by myself.

If you don't add the new option -dataFolder. The default folder of images dataset is /tiefvision/src/torch/data/encoded-images. Don't forget to move your images there.
