Smile Detection for User Interfaces

The mental state of a person is judged by detecting smiles. The smile detection starts with the facial recognition. The main advantage of the smile detection is it ensures whether smiles are detected by the camera or not. We compare those set of images and determine which image has the best smile. Now, across the mouth region to detect the corners we use Shi-Tomasi corner detection algorithm as reference and explained the results in detail in this paper.
