AdvCam-Hide-Adv-with-Natural-Styles

Code for "Adversarial Camouflage: Hiding Physical-World Attacks with Natural Styles" (CVPR2020)

[Paper link](https://arxiv.org/abs/2003.08757) ## Installation

Dependencies

• cuda==9.0.176
• cudnn==7.0.5

We highly recommend using conda.

conda create -n advcam_env python=3.6
source activate advcam_env

After activating virtual environment:

git clone https://github.com/RjDuan/AdvCam-Hide-Adv-with-Natural-Styles
cd AdvCam-Hide-Adv-with-Natural-Styles
pip install --user --requirement requirements.txt

Download VGG19.npy under folder /vgg19

Note: We use tensorflow v1 in the code, incompatible with python>3.6 when we test.

Usage

Quick Start

Running our given example:

sh run.sh

And the directory :

|--physical-attack-data
|  |--content
|    |--stop-sign
|  |--style
|    |--stop-sign
|  |--content-mask
|  |--style-mask

Note: we set iteration as 4000 for making sure a successful adversary, but adv with better visual performance can be found in earlier iterations.

Basic Usage

• Path to images
  • Put target image, style image, and their segmentations in folders. We set the name of target/style image and their segmentation are same by default.
  • Modify run.sh and advcam_main.py if you change the path to images.
  • We define the segmentation in following way, you can change it in utils.py

Segmentation type	RGB value
UnAttack	<(128,128,128)
Attack	>(128,128,128)

• Parameters

  • Parameters can be speicified in either run.sh or advcam_main.py.

• Run the follow scipt

sh run.sh

Usage example

A few motivating examples of how AdvCam can be used.

Adv Images

Three adverarial images generated by AdvCam with natural adversarial perturbation.

Physical Test

Google Image Test

Or use AdvCam to hide your image from Google Image Search Test image can be download here

More generation and test details can be found in video AdvCam

Q&A

• About the dataset.

Data is collected from ImageNet, open source imagehub and some are caputured by ourselves. Data used in our paper can be downloaded here. We provide both images and their masks (segmentaions).

Acknowledgments

• We use Yang's code for style transfer part.
• We use VGG19 implemented by Chris
