Extraction is a process of conversion of face features from the acquired digital image into a binary representation of the face, which is called a biometric template. Put simply, extraction is the process of generating a biometric template from the provided image.
In SmartFace, a template is generated from every detected face.
Generating the template
Biometric templates enable us to compare image data extremely fast and use the matching and grouping functionality.
In addition to the template, SmartFace Platform extracts various attributes, such as age, gender and additional information as the detection quality, coordinates of the face on the frame, position of the head defined by roll, pitch and yaw angles, etc. SmartFace Platform also provides information whether the detected person wears a facial mask.
