Abstract
Researchers in psychology, computer science, linguistics, neurology, and allied fields have become more interested in a human-computer interface system for autonomous face recognition or facial expression recognition. This study has recommended an Automatic Facial Expression Recognition System (AFERS). The proposed methodology consists of face detection, feature extraction, and facial expression identification processes. The initial phases of the face detection procedure include skin color identification using the YCbCr color model, illumination adjustment for face uniformity, and morphological operations for maintaining the required face region. Using the AAM (Active Appearance Model) approach, the first phase’s output is utilized to extract facial features such as the mouth, nose, and eyes. Automatic facial expression recognition is the third stage, and it is straightforward. Method of Euclidean Distance: This method compares the Euclidean distance between the feature points on the query image and the training images. The output picture expression is chosen based on the minimal Euclidean distance. This approach has a true recognition rate of between 90 and 95%. Utilizing the Artificial Neuro-Fuzzy Inference System (ANFIS), this method is further modified. In comparison to previous systems, this non-linear recognition system provides a recognition rate of close to 100%, which is satisfactory.
