deep learning - How to load images and labels in Torch for a Convolutional Neural Network -

i'm new torch , load images 2 directories (one each label). i'm trying build convolutional neural network classify images belonging 1 class or (i.e. binary classifier) unsure how load images, label images , data correct format. i'm using following tutorial, training data loaded in different way not familiar with.

hope can me started , point me in right direction.

many in advance.

check this link data.lua file in simple understand. have used torch tensors, , code self explanatory. had achieved clear understanding of loading data, post reading link; hope helps too.
