%X A new method of feature extraction for visual signal is presented in this paper. The signal of the image projection, which is acquired by CCD, is transformed with wavelet. And the zero cross point of transform is located at the center of the image when the scale of wavelet is suitable. The experiment shows that the method possesses stronger robustness for stochastic error disturbance than other methods do.
