FACIAL EXPRESSION RECOGNITION SYSTEM AND METHOD USING MACHINE LEARNING

摘要

The present invention relates to a face expression recognition system using machine learning and a method for the same. Specifically, the face expression recognition system includes: a detecting module detecting a face area of a user in a video including a face of the user which is input; an extraction module extracting a feature vector on the face of the user from the face area; a classification module classifying the face of the user by using the feature vector; and a recognition module recognizing a face expression of the user from the face of the user. Also, specifically, the face expression recognition system includes: (1) a step in which the detecting module detects the face area of the user in the video including the face of the user which is input; (2) a step in which the extraction module extracts the feature vector on the face of the user from the face area; (3) a step in which the classification module classifies the face of the user by using the feature vector; and (4) a step in which the recognition module recognizes the face expression of the user from the face of the user. According to the present invention, the face expression recognition system using machine learning can improve speed of recognizing the face expression of the user in comparison with an existing face recognition technique.
