Query: Adversarial Rain Attack and Defensive Deraining for DNN Perception   Rain often poses inevitable threats to deep neural network (DNN) based
perception systems, and a comprehensive investigation of the potential risks of
the rain to DNNs is of great importance. However, it is rather difficult to
collect or synthesize rainy images that can represent all rain situations that
would possibly occur in the real world. To this end, in this paper, we start
from a new perspective and propose to combine two totally different studies,
i.e., rainy image synthesis and adversarial attack. We first present an
adversarial rain attack, with which we could simulate various rain situations
with the guidance of deployed DNNs and reveal the potential threat factors that
can be brought by rain. In particular, we design a factor-aware rain generation
that synthesizes rain streaks according to the camera exposure process and
models the learnable rain factors for adversarial attack. With this generator,
we perform the adversarial rain attack against the image classification and
object detection. To defend the DNNs from the negative rain effect, we also
present a defensive deraining strategy, for which we design an adversarial rain
augmentation that uses mixed adversarial rain layers to enhance deraining
models for downstream DNN perception. Our large-scale evaluation on various
datasets demonstrates that our synthesized rainy images with realistic
appearances not only exhibit strong adversarial capability against DNNs, but
also boost the deraining models for defensive purposes, building the foundation
for further rain-robust perception studies.
