The POST request (see Search request) used for search start must contain binary data of searched face in jpеg format.
Note
All face detection triggerings are stored in the t_json_event database table.
The t_face_vector table stores the vectors of faces recognized by the detection tool.
The t_face_listed table stores the face images added to the list of people.
| Parameter | Required | Description |
|---|---|---|
| accuracy | No | The accuracy parameter is a recognition rate from range [0, 1] (1 – complete match). This parameter is specified additionally in the search line or in the request body. Otherwise, the default value 0.9 will be used. Attention! The parameter value specified in the request body has higher priority. |
Attention!
If the body of the POST request is empty, then the search will return all the results for the recognized faces. The accuracy parameter value in this case will be 0.
