An Application Study on Facial Expression Recognition Based on Gabor Wavelets

The expression of Gabor wavelet filter is provided, it is explored in detail. In according to actual demand, a new multichannel filter based Gabor wavelet is designed based on theory and practicality. Its center frequency is the range from low frequency to high frequency, its orientation is 6 and scale is 6. It can extract the feature of low quality facial expression image target, and have good robust for automatic facial expression recognition. Experimental results show that the performance of the proposed method is excellent when it is applied to facial expression recognition system.
