The specific goal here is more to detect crude near duplicate image manipulations than to perform object or scene retrival.

# Usage


This library was created to benchmark all these different methods. The easiest way for this is to choose a dataset, randomly split it in 2 parts (experimental and control groups), and sample a given number of images in both groups on which you can perform artificial attacks defined in `generator/generate_attacks.py`. The scripts `create_groups.py` and `create_attacks.py` perform those tasks, and save the images with correct name format for later matching.

Then given a database of images, an experimental group of images that are manipulations of some images in the database (all attacks on the images sampled from experimental group) and a control group containing images not present in the database (all attacks on the images sampled from control group), datasets can be declared in the following way :
