Group two graylevel images back-to-back and treat it as a 2-channel image in caffe

[Saeed Izadi]

Hi,

I want to group two grayscale images back-to-back and treat this structure as a 2-channel image, and train a network on the obtained dataset. How can I feed the a 2-channel image for training in caffe?

thanks

A concatenation layer can combine channels in that way.
