  name: Seventh Sense Collections API
  description: Collections are groups of registered `Persons`. You can use collections to organize your registered persons
    and to search for persons within a specific collection. You can also use collections to manage access to your registered
    persons. For example, you can create a collection for each of your customers/organization sub-units and only allow them
    to search for persons in their own collection.

  name: Seventh Sense Face Anti-Spoofing / Liveness API
  description: The `/liveness` endpoint allows you to determine if a face image is of a real person or a spoofed image (eg.
    a printed image of a face, or an image captured from a tablet's screen). The endpoint returns a score between 0 and 1,
    where 1 is a real person and 0 is a spoofed image, the threshold for the image to be considered live is >= 0.5.<br/><br/>
    Our liveness achieved Attack Presentation Classification Error Rate (APCER) of 0% and reached iBeta Level 2 compliance
    in accordance with ISO 30107-3. <br/><br/>**Note:** The `/liveness` endpoint does not store any information on our servers.
    It is a one-time classification of an image using a deep learning model. 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 `/search` endpoint.<br/><br/>To
    ensure fraudsters cannot use high-resolution print outs, masks or video playbacks to spoof face recognition systems, liveness
    image has a higher requirement on image:<br/><br/>Liveness image requirement:<br/> <ul> <li>There should only be one main
    face on the image. It should be fully visible within a frame and fully open without any occlusions. No crop is allowed.
    Small faces in the background are not taken into account.</li> <li>The minimum size of a face box that can be processed
    is 224x224 pixels.</li> <li>The padding between the face box and the image's borders should be at least 25 pixels.</li>
    <li>The distance between the pupils on the face should be at least 80 pixels.</li> <li>The out-of-plane rotation angle
    (face pitch and yaw) should be no more than ±30 degrees.</li> <li>Fish-eye lenses and sunglass images are not supported.</li>

  description: 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. <br/><br/>**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.

    person's name and/or add additional images to the registered person. Registering a person stores thumbnail face images
    and information on our servers. You can delete a registered person using the `DELETE /person/{person_id}` endpoint.

  description: 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.<br/><br/>**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.
