| Approximate Garbage Score (AGS) |
A BestShotQuality estimator component that determined the source image score for further descriptor extraction and matching. Estimation output is a float score which is normalized in range [0..1]. The closer score to 1, the better matching result is received for the image. |
| Best shot |
The frame of the video stream on which the face is fixed in the optimal angle for further processing. |
| Descriptor |
Data set in closed, binary format prepared by recognition system based on the characteristic being analyzed. |
| Estimator |
Neural network used to estimate a certain parameter of the face in the source image. |
| Eye estimation |
Estimator that determines an eye status (open, closed, occluded) and precise eye iris and eyelid location as an array of landmarks. |
| Face |
Changeable objects that include information about a human face. |
| Handler |
Set of rules or policies that describe how to process the received images. |
| Landmarks |
Reference points on the face used by recognition algorithms to localize the face. |
| 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). |
| LUNA PLATFORM |
Automated face and body recognition system that allows you to perform face detection, Liveness check biometric template extraction, descriptor extraction, quality and attribute estimation, such as gender, age, and so on, on images using neural networks. |
| Matching |
The process of descriptors comparison. Matching is usually implemented as a distance function applied to the feature sets and distances comparison later on. The smaller the distance, the closer are descriptors, hence, the more similar are the objects. |
| Occlusion |
State of an object (eye, mouth) when it is hidden by any other object. |
| Samples, Warps |
Normalized (centered and cropped) image obtained after face detection, prior to descriptor extraction. |
| Verification |
Comparison of two photo images of a face in order to determine belonging to the same face. |
| Verifier |
Specifies a list of rules for processing and verifying incoming images. Unlike handlers, it not only processes, but also verifies the images. |
