Adversarial examples are intentionally perturbed images that mislead classifiers.

This paper introduces a divide-and-conquer inspired adversarial learning (DACAL) approach for photo enhancement.

On the top level, we propose a perception-based division…

Batch Normalization (BN)(Ioffe and Szegedy 2015) normalizes the features of an input image via statistics of a batch of images and hence BN will bring the noise to the gradient of the training loss. Previous works indicate that the noise is important for the optimization and generalization of deep neural networks, but …
