The aim of undouble is to detect (near-)identical images. It works using a multi-step process of pre-processing the images (grayscaling, normalizing, and scaling), computing the image hash, and the grouping of images. A threshold of 0 will group images with an identical image hash. The results can easily be explored by the plotting functionality and images can be moved with the move functionality. When moving images, the image in the group with the largest resolution will be copied, and all other images are moved to the undouble subdirectory. In case you want to cluster your images, I would recommend reading the blog and use the clustimage library.

The following steps are taken in the undouble library:

  • Read recursively all images from directory with the specified extensions.
  • Compute image hash.
  • Group similar images.
  • Move if desired.

Installation

It is advisable to create a new environment (e.g. with Conda).
conda create -n env_undouble python=3.8
conda activate env_undouble
Install bnlearn from PyPI
pip install undouble            # new install
pip install -U undouble         # update to latest version
Directly install from github source
pip install git+https://github.com/erdogant/undouble
Import Undouble package
from undouble import Undouble

Examples:

# -------------------------------------------------
# >You are at the point of physically moving files.
# -------------------------------------------------
# >[7] similar images are detected over [3] groups.
# >[4] images will be moved to the [undouble] subdirectory.
# >[3] images will be copied to the [undouble] subdirectory.

# >[C]ontinue moving all files.
# >[W]ait in each directory.
# >[Q]uit
# >Answer: w

The input can be the following three types:

* Path to directory
* List of file locations
* Numpy array containing images
