In plain words: A model that ties neighboring image pieces together sets the layout of high-level features from a deep image network to guide generation. It avoids artifacts and implausible feature mixtures better than earlier network-based reconstruction, and unlike classic texture synthesis it can vary local features.

Abstract · Combining Markov Random Fields and Convolutional Neural Networks for Image Synthesis

This paper studies a combination of generative Markov random field (MRF) models and discriminatively trained deep convolutional neural networks (dCNNs) for synthesizing 2D images. The generative MRF acts on higher-levels of a dCNN feature pyramid, controling the image layout at an abstract level. We apply the method to both photographic and non-photo-realistic (artwork) synthesis tasks. The MRF regularizer prevents over-excitation artifacts and reduces implausible feature mixtures common to previous dCNN inversion approaches, permitting synthezing photographic content with increased visual plausibility. Unlike standard MRF-based texture synthesis, the combined system can both match and adapt local features with considerable variability, yielding results far out of reach of classic generative MRF methods.
