Neural Nearest Neighbors Networks

NeurIPS 2018 Tobias PlötzStefan Roth

Non-local methods exploiting the self-similarity of natural signals have been well studied, for example in image analysis and restoration. Existing approaches, however, rely on k-nearest neighbors (KNN) matching in a fixed feature space... (read more)
