Code accompanying the paper "Expecting the Unexpected: Training Detectors for Unusual Pedestrians with Adversarial Imposters(CVPR2017)". As for the generator for synthetic data, please take this repo for reference.

• ubuntu or Mac OS
• tensorflow==0.12.0+(with GPU)
• pip install image
• image_pylib(This repository should be put under the same folder with RPNplus.)

Run Demo:

• Download model files(RPN_model & VGG16_model) first, and put them in the ./models/ folder.
• The number 0 is your GPU index, and you can change to any available GPU index.
• This demo will test the images in the ./images/ folder and output the results to ./results/ folder.

python demo.py 0

Train:

• The number 0 is your GPU index, and you can change to any available GPU index.
• Open train.py and set imageLoadDir and anoLoadDir to proper values(imageLoadDir means where you store your images and anoLoadDir means where you store your annotation files).

python train.py 0
