Abstract
AbstractDeep convolutional neural networks (DCNNs) have been widely deployed in real-world scenarios. However, DCNNs are easily tricked by adversarial examples, which present challenges for critical applications, such as vehicle classification. To address this problem, we propose a novel end-to-end convolutional network for joint detection and removal of adversarial perturbations by denoising (DDAP). It gets rid of adversarial perturbations using the DDAP denoiser based on adversarial examples discovered by the DDAP detector. The proposed method can be regarded as a pre-processing step—it does not require modifying the structure of the vehicle classification model and hardly affects the classification results on clean images. We consider four kinds of adversarial attack (FGSM, BIM, DeepFool, PGD) to verify DDAP’s capabilities when trained on BIT-Vehicle and other public datasets. It provides better defense than other state-of-the-art defensive methods.
