摘要
Based on using the whole curve′s feature, the authors proposed the preliminary technologies of weighted absorption peaks to enhancing the single diagnostic feature.Using the part of data from the standard spectral library PMS,the authors has accomplished some experiments based on the dissimilarity of mineral.Because the technology used whole mineral features and highlighted the important features,the description of mineral was more comprehensive and accurate.Meanwhile,the technology applied the continuum removes algorithms to reduce the effects of back noise.
