Based on statistical characteristics of nuclear spectrum
statistical model
namely Gaussian mixture model(GMM)
was adopted for smoothing filtering of nuclear spectrum.The main idea for this method is to do function approximation of nuclear spectrum using good approximating performance of GMM
build mathematical model of original spectrum based on GMM
and realize more reasonable smoothing filtering of spectrum in the process of multiple operation by this model.
