Our face detection API detects the existence and location of faces in an image or video, identifies facial landmarks.
Our face detection technology is highly reliable and accurate in detecting human faces in different applications. Detecting faces in an image has multiple applications, but combining them with other APIs provided by SmartClick (such as age estimation, face recognition, etc.), the technology has larger value and more use cases.
Try Model
Main Function
Face Detection API localizes all the human faces in a frame and returns the coordinates of the faces. Using this API, you can find faces in an image and crop them out. With this technology, you can apply other APIs we have developed, such as face recognition, age detection, etc.
The APIs to Use with Face Detection Include:
Recognizes and locates facial features and returns the coordinates of the person’s major features with 64 points on the face.
Age Detector
Identifies the approximate age of a person using features of the face, such as eye corners, lips, and nostrils.
Emotion Detection
Determines human emotions based on facial expressions and changes in facial gestures.
Head Pose Estimation
Calculates the coordinates of the person’s nose, mouth, eyes, and other facial features and provides the direction a person is facing.
Monitors the direction where a person is looking based on pupil and iris position.
Input
The input is an image.
Output
The API returns the following:
Probability – A probability of the detected cropped region being a face
Rectangle – A location of the detected face in the form of the top-left and bottom-right pixel coordinates of the frame
Margin Rectangle – The size of the rectangle around the detected face
Landmarks – localize and represent salient regions of the face. Returns the following:
- Left_eye
- Right_eye
- Nose
- Mouth_left
- Mouth_right
