Adversarial Color Enhancement: Generating Unrestricted Adversarial Images by Optimizing a Color Filter

Zhao, Zhengyu, Liu, Zhuoran, Larson, Martha

Understand

We introduce an approach that enhances images using a color filter in order to create adversarial effects, which fool neural networks into misclassification.

  • Our approach, Adversarial Color Enhancement (ACE), generates unrestricted adversarial images by optimizing the color filter via gradient descent.
  • The novelty of ACE is its incorporation of established practice for image enhancement in a transparent manner.
  • Experimental results validate the white-box adversarial strength and black-box transferability of ACE.
