Seventh Sense

Seventh Sense Face Verification API

The `/compare` endpoint allows you to compare two sets of face images to determine if they correspond to the same person. A score higher than 0.81 is a good indicator that the two sets of images belong to the same person. You can also use a score of 0.75 or higher if the images are of the same person but taken at different times (years apart). The score is a number between 0 and 1, where 1 is a perfect match and 0 is a perfect mismatch. The score is calculated using a deep learning model trained on millions of face images. **Note:** The `/compare` endpoint does not store any information on our servers. It is a one-time comparison of two sets of images. If you want to store the images and search for them later, use the `/person` endpoints to manage persons for a later search using the `/search` endpoint.
