Image API consists of services available via REST API.

Service Name	Functions
gateway	The service is responsible for getting access to Image API and interacting with the processing services listed below.
body-detector	The service is designed to detect bodies in an image. The detection result is the coordinates of the bounding box (bbox) around the detected body.
face-detector-face-fitter	The service is used to determine the anthropometric points and the head rotation angles. The returned result is a set of 21 anthropometric points and the values of head rotation angles (yaw, pitch, roll).
emotion-estimator	The service estimates emotions from a face image. The result is the degree of manifestation of each estimated emotion.
age-estimator	The service estimates a person’s age from a face image. The estimation result is the numerical value of the person's age.
gender-estimator	The service is used to determine a person’s gender from a face image.
face-detector-liveness-estimator	The service is used to detect if a person in an image is real or fake. The result is a Real/Fake verdict with a numerical value of confidence.
mask-estimator	The service detects if a person in an image is wearing a medical mask. The result is a True/False verdict with a numerical value of confidence.
quality-assessment-estimator	The service is designed to estimate the quality of a face image. The result is a list of detected faces with a detailed image quality analysis.
verify-matcher	The service compares two face images to determine if they belong to the same person.
face-detector-template-extractor	The service is designed to extract a biometric template from a face image.
