Large Image Datasets Today are a Mess | Blog Post | Video Tutorial
FastDup is a tool for gaining insights from a large image collection. It can find anomalies, duplicate and near duplicate images, clusters of similarity, learn the normal behavior and temporal interactions between images. It can be used for smart subsampling of a higher quality dataset, outlier removal, novelty detection of new information to be sent for tagging. FastDup scales to millions of images running on CPU only.

Duplicates and near duplicates identified in MS-COCO and Imagenet-21K dataset
Thousands of broken ImageNet images that have confusing labels of real objects.
IMDB-WIKI outliers (data goal is for face recognition, gender and age classification)
Can you tell how many different persons?
Wrong labels in the Imagenet-21K dataset.
Cluster of wrong labels in the Imagenet-21K . No human can tell those red wines from their image.
Fun labels in the Imagenet-21K dataset
Upcoming new features: image graph search!
Results on Key Datasets (full results here)
We have thoroughly tested fastdup across various famous visual datasets. Ranging from pilar Academic datasets to Kaggle competitions. A key finding we have made using FastDup is that there are ~1.2M (!) duplicate images on the ImageNet-21K dataset, out of which 104K pairs belong both to the train and to the val splits (this amounts to 20% of the validation set). This is a new unknown result! Full results are below. * train/val splits are taken from https://github.com/Alibaba-MIIL/ImageNet21 .

- Experiments presented are on a 32 core Google cloud machine, with 128GB RAM (no GPU required).
- All experiments could be also reproduced on a 8 core, 32GB machine (excluding Imagenet-21K).
- We run on the full ImageNet-21K dataset (11.5M images) to compare all pairs of images in less than 3 hours WITHOUT a GPU (with Google cloud cost of 5$).
For Python 3.7 and 3.8 (Ubuntu 20.04 or Ubuntu 18.04 or Mac M1 or Mac Intel Mojave and up)
python3.8 -m pip install fastdupimport fastdup
fastdup.run(input_dir="/path/to/your/folder", work_dir='out') #main running function
fastdup.create_duplicates_gallery('out/similarity.csv', save_path='.') #create a visual gallery of found duplicates
fastdup.create_outliers_gallery('out/outliers.csv', save_path='.') #create a visual gallery of anomalies
fastdup.create_components_gallery('out', save_path='.') #create visualiaiton of connected components
