Toward Practical Smile Detection

J. Whitehill, G. Littlewort, I. Fasel, M. Bartlett, J. Movellan
2009 IEEE Transactions on Pattern Analysis and Machine Intelligence  
Results suggest that human-level expression recognition accuracy in real-life illumination conditions is achievable with machine learning technology.  ...  However, to date, nearly all automatic facial expression recognition research has focused on optimizing performance on a few databases that were collected under controlled lighting conditions on a relatively  ...  While this difference was statistically significant (tð152Þ ¼ 4:53; p < 0:05), in practice it was very difficult to differentiate human and machine codes.  ...
