Person-independent expression recognition based on images adjusted by Hopfield network
Zilu Ying · Computer Engineering and Applications Journal · 2008
In this paper,a new method adjusted by Hopfield network is proposed for expression recognition.First,a standard expression images should be selected for training of Hopfield network.Then,when Hopfield network had been trained,all expression images would be adjusted to close with similar standard images.This would increase distances between seven expression images.It would benefit for expression recognition.Experiment result shows this method can highly improve recognition rates.
