Clustering Images

API for grouping images on similarity.

Optional you can sample your image set based on clusters. Sampling your images makes sense if you have a hugh amount of them and wanna label only a subset by using an image labeling tool.

Prerequisites:

• docker
• docker-compose

Check for prerequisites

To check if docker-ce is installed:

docker --version

To check if docker-compose is installed:

docker-compose --version

Install prerequisites

Ubuntu

sudo docker-compose up --build

API Endpoints

To see all the available endpoints, open your favorite browser and navigate to:

http://<machine_IP>:5002/docs

You can change the port in the docker compose file.

/download_web_images (POST)

This endpoint takes a search query and downloads corresponding images from google, bing and yahoo.

Images will be saved to the mounted input directory, which can be changed in the docker compose file:

├──exchange/
    ├── input/
        ├── *.jpg
        ├── *.jpeg
        ├── *.png

The endpoint returns an overview of all downloaded images. For example when searching for 'germany':

/get_amount_of_clusters (POST)

This endpoint takes the image set from the mounted input directory and returns the result of the elbow method for choosing the best amount of clusters:

Please place files in the mounted input directory.

├──exchange/
    ├── input/
        ├── *.jpg
        ├── *.jpeg
        ├── *.png

/cluster_images (POST)

This endpoint takes the image set from the mounted input directory and groups them based on similarity.

In addition you have the opportunity to get a sample of your image set by choosing x percentage of each image cluster.

Please place files in the input directory. The output directory will be generated automaticly:

├──exchange/
    ├── input/
    │   ├── *.jpg
    │   ├── *.jpeg
    │   ├── *.png
    │
    ├──output/
        ├── cluster_0/
        │   ├── *.jpg
        │   ├── *.jpeg
        │   ├── *.png
        ├── cluster_1/
        │   ├── *.jpg
        │   ├── *.jpeg
        │   ├── *.png
        ├── sample/
            ├── *.jpg
            ├── *.jpeg
            ├── *.png

The endpoint returns an overview of the image clusters:
