Visualize not working

[jvpoulos]

I'm using this code to train on the Washington Database, which contain binarized and normalized cropped images like this:

which has a ground-truth label of 'williamsburgh'.

With default settings, I do well during training (loss 0.001056, perplexity 1.00) but at test time get a very low character accuracy (11%).

When I visualize on the test set, I'll get blank images returned

even when the translation is correct word.txt

Fixed image loading to work with binary images
