Visualize Layers in VGG19

VGG19 is a pretrained network that was originally developed to do image classification, but it has gained a lot of popularity for its usefulness in aiding the training of other networks. It is used in style transfers, deep dreaming, image enlargement and numerous other applications. All of these applications extract layers from VGG19 to work. I recently needed to see what was happening in some layers for a style transfer network I am developing. I decided to share the application I built here in hopes it will help others with a similar need.

An example is preloaded with the famous Lenna image. Feel free to load your own image to see what the VGG19 network sees with it.
