Abstract :
Wavelet analysis is applied to process energy spectrum signal of drug detection by energy scattering X-Ray. In the paper, we put forward a novel algorithm of adaptive correlation filtration, which could achieve better filter effect. In addition, a simple and effective method of peaks seeking is designed, which might achieve both strong peaks and weak peaks. Eventually, comparing experiment result with data by XRD and PDF, it makes out low relative error.
