Seventh Sense

Seventh Sense Search API

The endpoints below allow you to search for previously registered persons using a face image obtained at a later time. The search is performed using a deep learning model trained on millions of face images. The search results are ranked by the similarity score, which is a number between 0 and 1, where 1 is a perfect match and 0 is a perfect mismatch. The search results are returned in order of decreasing similarity score, but above the specified `min_score` threshold (default is 0.81). The `max_results` parameter is optional and allows you to control the maximum number of returned results. By default, it is set to 10, but you can customize this number for your specific use case. The maximum value you can set is 100.**Note:** The `/search` endpoint does not store any information on our servers. It is a one-time search of a set of images against registered persons. If you want to store the images and search for them later, use the `/person` endpoint to register persons for a later search using the endpoints below.
