How this classifier works

To start, upload your image. Our AI tool will then predict if it has a stamp.

This pretrained image model uses a Nyckel-created dataset and has 2 labels, including Has Stamp and No Stamp.

We'll also show a confidence score (the higher the number, the more confident the AI model is around if it has a stamp).

Whether you're just curious or building if a postcard has a stamp detection into your application, we hope our classifier proves helpful.
