Installation

The code requires Python 3.x and Tensorflow 1.2.1 .

To install Python 3.x for Ubuntu, you can run:

apt-get update
apt-get install -y python3.5 python3.5-dev python3-pip python3-venv

We recommend to use a virtual environment:

python3.5 -m venv ../venv
source ../venv/bin/activate
pip install --upgrade pip

Installation with GPU

Install Cuda8 and Cudnn5, more informetion on sites:

• https://developer.nvidia.com/cuda-downloads
• https://developer.nvidia.com/cudnn

Then install the requested libraries using:

cat noiseprint/requirements-gpu.txt | xargs -n 1 -L 1 pip install

Installation without GPU

Install the requested libraries using:

cat noiseprint/requirements-cpu.txt | xargs -n 1 -L 1 pip install

Usage

To extract the noiseprint, run:

python main_extraction.py <input image> <output mat/npz file>

The noiseprint is saved in a file with extension mat or npz. To show the saved noiseprint, run:

python main_showout.py <input image> <output mat/npz file>

While to execute the blind localization method, run:

python main_blind.py <input image> <output mat/npz file>

The heatmap is saved in a file with extension mat or npz. To show the result, run:

python main_showres.py <input image> <gt image> <output mat/npz file>

To convert the heatmap in a png image, run:

python main_map2uint8.py <output mat/npz file> <output png file>

Demo

To execute the demo, run the script

cd ./demo
./demo_extraction.sh
./demo_heatmap.sh
