Term Description
Attributes Basic attributes and descriptor.
Basic attributes Age, gender, and ethnicity.
Body parameters Body characteristics (presence of backpack, headwear, color of clothing, etc.) determined on the source image during detection.
Bounding box Rectangle that bounds the image space with the detected face or body.
Bucket Logical entity used to store objects.
Cooperative mode Process of obtaining source photo images of faces or boies from videostream with conscious person interaction with the camera.
Descriptor Data set in closed, binary format prepared by recognition system based on the characteristic being analyzed.
Detector Neural network used to detect either faces or bodies, or both faces and bodies in the source image.
Estimator Neural network used to estimate a certain parameter of the face or body in the source image.
Face Changeable objects that include information about a human face.
Face parameters Facial characteristics (emotions, mouth parameters, head position, etc.) determined on the source image during detection.
Image parameters Image characteristics (width and height, aspect ratio, size, etc.) determined on the source image during detection.
Landmarks Reference points on the face or body used by recognition algorithms to localize the face or body.
Liveness Software method that enables you to confirm whether a person in one or more images is "real" or a fraudster using a fake ID (printed face photo, video, paper or 3D mask).
Matching The operation of matching descriptors stored in the database.
