Smile, you're on identity camera
نویسندگان
چکیده
Inspired by recent advances in psychological studies on motion-based face perception, we examine in this paper, from the viewpoint of pattern recognition, the identity information behind a smile. A smile video database is collected, from which we compute dense optical flow fields and generate features by summing up the flow fields over time during the neutral-to-smile period. We investigate the relationship between smiles and identity by studying the class separability of the features. Our experiment results indicate a strong identityspecific characteristic of smile dynamics. Moreover, we compare the discriminating power of the features generated from different face regions as well as from different periods of motion.

متن کاملSmile 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...
