Face emotion recognition is a topic in medical forensic for the analysis of human feelings in the face. Face recognition has been in implementation for a long time. Advancing further, human feeling as expressed by the human faces and felt by the brain can be replicated in the video, visual form, or electronic signals (like EEG). Through this article, you can get a complete picture of Facial Emotion Algorithm using Machine Learning Project. Let us first start with the significant characteristics features for emotion recognition.

Current artificial intelligence-based platforms need to be able to replicate and evaluate emotions from human faces, therefore emotions detection is very important. This could help you to make more informed choices decisions, whether it’s about determining intent, promoting deals, or avoiding security risks. 

Detecting feelings from photos or video is a simple operation for the unaided human eyes, but it is a difficult challenge for robots, requiring a variety of image processing methods for extracting features. 

What are the important features that can be used in Emotion Recognition? 

• Geometrical facial features   
  • A collection of nineteen traits that are more attributed to human emotions was chosen experimentally by analyzing certain positions on the individual’s face.
  • Those Nineteen attributes are a component of a markerless system enabling feature recognition and positioning that already exists.
• Eccentricity features
  • The idea of ellipses is used to define eccentricity traits.
  • The eccentricity of an ellipse is the distance the ellipse deviates from just being a circular one
  • For elliptical features, eccentricity ranges from 0 to 1, with zero being the case if the ellipse turns into a circle.
  • Eccentricity would be larger than Zero when looking smiley, although it becomes closer to zero when exhibiting astonishment.
•  Linear movements
  • Quantitative evaluation of distances among facial landmark positions due to movement at the time of expressing emotions is called the normalized linear distances
  • The following are the linear feature vectors and their calculations
    • L3 represents the movement between eyebrows and eyes
    • L2 represent the movements between nose and mouth
    • L1 denotes the movement between lower and upper mouth points
