We present Stacked U-Nets, and neural net architecture that combines the information globalization properties of multigrid solvers with the expressive power of neural nets. Stacked U-Nets achieve state of the art performance on natural image segmentation (the Pascal VOC benchmark) using an order of magnitude fewer parameters than more complex models.
