An infrared-spectrum based feature extraction method for identifying Chinese herbal origins and growth mode with high-recognition rate

總結: 中藥的歷史悠久，療效顯著，副作用相比於西藥少。近年, 西方國家亦漸漸趨向中醫藥的研究。然而由於中藥材在市場上存在品質問題，此對中醫藥的信譽、療效和人們的生命健康帶來了不良的後果。因此，中藥材的品質鑒定在中藥療效、安全及發展中扮演極其重要的角色。目前，中藥材的鑒別主要依賴觀察者的經驗或理化方式。前者方法誤差機率大; 後者方法相當複雜、費時、成本高，並且重複性低。本發明可通過紅外光譜，鑒定中藥材的品質、成分的比例、來源地及生長方式。

詳細技術說明: 本發明的優點在於，本地用戶可用光譜儀直接將待識別的實物樣本的紅外譜數據輸入系統。系統中的專用軟件將根據已建立的數據庫，進行探索及處理後，以文字和圖形形容顯示給用戶，以達到其目的。
