Parameters

image: image file

Response

result: face liveness, attribute check result

liveness_score: liveness score of detected face

face_rect: face bounding box of detected face

angles: Pitch, Yaw, Roll of detected face

POST /api/check_liveness_base64

Perform face liveness detection and attribute analysis on a base64 image

Parameters

image: base64 image

Response

result: face liveness, attribute check result

liveness_score: liveness score of detected face

face_rect: face bounding box of detected face

angles: Pitch, Yaw, Roll of detected face
