FACIAL FEATURE EXTRACTION FOR SMILE DETECTION

Abstract

The mental state of a person isjudged by detecting smiles. The smile detection starts with the facial recognition. Smile detectionfrom facial images is a specialized task in facial expression analysis with many potential applications such as smiling payment, patient monitoring and photo selection. The current methods on this"study are to represent face with low level features, followed by a strong classifier. In this project, we propose to extract smiles and non smiles by using MATLAB. A key contribution ofthis work is that we both recognition and verification as supervision which is helpful to in smile detection.
