It is very attractive to formulate vision in terms of pattern theory \cite{Mumford2010pattern}, where patterns are defined hierarchically by compositions elementary building blocks. But applying real world images currently less successful than discriminative methods such as deep networks. Deep networks, however, black-boxes which hard interpret and can easily be fooled adding occluding objects. natural wonder whether better understanding networks we extract blocks used develop theoretic...

Deep generative models have shown promising results in generating realistic images, but it is still non-trivial to generate images with complicated structures. The main reason that most of the current fail explore structures including spatial layout and semantic relations between objects. To address this issue, we propose a novel deep structured model which boosts adversarial networks (GANs) aid structure information.
