A Method Based on Wavelet Transform for Mineral Spectral Characteristics Extraction

摘要

The basic principle of the wavelet analysis method to extract the mineral spectral absorption characteristics is summarized and different wavelet bases, wavelet decomposition scale extraction effect are analyzed in this paper. Then, the algorithm of mineral spectral absorption characteristics based on wavelet spectral analysis is provided and a large number of experiments are carried out using the spectrums of field rock mineral. Experimental result shows that such a method is less affected by original signal noise and depict the parameters of the mineral spectral absorption feature more precise, which is an ideal spectral feature extraction method compared with the traditional mineral spectral absorption feature extraction method.
