A set of luminance stickers were fixed on subject's face and the subject is instructed to perform required facial expressions. At the same time, subject's expressions are recorded in video. A set of 2D coordinate values are obtained by tracking the movements of the stickers in video using tracking software. Daubechies wavelet transform with different orders (db1 to db20) performed on obtained data. Standard deviation is derived from wavelet approximation coefficients for each daubechies wavelet orders. This standard deviation is used as an input to the neural network for classifying 8 facial expressions. 2010-11-25T06:15:28Z 2010-11-25T06:15:28Z 2010-05-21 Working Paper 978-1-4244-7122-5 http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5545262 http://hdl.handle.net/123456789/10306 en Proceedings of the 6th International Colloquium on Signal Processing and Its Applications (CSPA) 2010 Institute of Electrical and Electronics Engineers (IEEE) |
