#### Error messages

| Error                          | Description                                                                                                                          |
| ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------ |
| FACE\_TOO\_CLOSE               | A distance between face and camera is too small for preprocessing issues                                                             |
| FACE\_CLOSE\_TO\_BORDER        | Face is too close to one or more borders. May reduce the accuracy of spoofing detection because edges of face may not be seen        |
| FACE\_CROPPED                  | Face is cropped. May reduce the accuracy of spoofing detection because edges of face may not be seen                                 |
| FACE\_IS\_OCCLUDED             | There is occlusion on the face or it is difficult to see face, which degrades the quality of liveness                                |
| FACE\_NOT\_FOUND               | Face detector can't find face on image                                                                                               |
| TOO\_MANY\_FACES               | Face detector found more than one face on image                                                                                      |
| FACE\_TOO\_SMALL               | Facial area is not big enough for analysis. Either interpupillary distance(80px) or face size(224 px) is below the configured value. |
| FACE\_ANGLE\_TOO\_LARGE        | Facial out-of-plane rotation angle is extremely large                                                                                |
| FAILED\_TO\_PREDICT\_LANDMARKS | Landmarks prediction error                                                                                                           |
