| Parameter | Required | Description | |||||
|---|---|---|---|---|---|---|---|
| accuracy | No | Sets face similarity level in the range [0,1] (1 means complete match). If this parameter is not set, then the default value (0.9) is in use. If the compared face was in the camera field of view FOV on a specific day and it was recognized with accuracy that is not less than the specified one, then this face is considered to be present on that day. Otherwise, the algorithm considers this face was absent on that day.
| |||||
| threshold | No | Defines Determines the threshold value to recognize a face as a “stranger”. The value is set in the range from 0 to 1, and it defines determines the number of days within which the face was absent to be considered as a “stranger”: 30-30*threshold. For instance, the value 0.8 means “the required object appeared in the search area within (30 - 30 * 0.8 = 6) days”. All faces that appeared within 6 and more days will be defined as “familiar faces”, others – —as “strangers”.
| |||||
| op | No | Defines Determines the search direction. Allowable values: lt – —“familiar face” search (based on the threshold parameter). gt – “stranger” —“stranger” search. |
