摘要：目的 對新疆維吾爾醫(yī)植物藥材圖像進行特征提取，并對所研究特征進行分析，探討其在維吾爾醫(yī)藥材圖像分類中的效果，找到適用于維吾爾醫(yī)藥材圖像分類的特征，為基于內(nèi)容的新疆維吾爾醫(yī)藥材圖像的檢索系統(tǒng)奠定基礎。方法 以新疆維吾爾藥材中植物藥的花和葉為研究對象，先對圖像進行預處理，進而提取顏色和紋理特征作為原始特征，并對特征進行統(tǒng)計學分析，運用最大類間距法篩選得到圖像分類的主要特征，最后應用Bayes判別分析法對特征的分類能力進行評價。結(jié)果 將顏色特征和紋理特征篩選后進行分類，花類圖像的分類準確率為85%，葉類圖像的分類準確率為62%。利用篩選后的特征對花類圖像的分類效果好于利用原始特征分類的效果。結(jié)論 與原始特征分類比較，運用篩選后的特征進行分類，對于判別花類藥材的效果較好。這為進一步研究維吾爾醫(yī)藥材圖像分類和完善特征提取方法奠定了基礎。

　　Abstract： Objective To extract Xinjiang Uyghur medicine image features and analyze the features； To investigate the image classification effect of the researched features； To find the suitable features for Xinjiang Uyghur medicine image classification； To lay the foundation for content-based medical image retrieval system of Xinjiang Uyghur medicine images. Methods The flowers and leaves of Xinjiang Uyghur medicine were treated as the research objects. First， images were under preprocessing. Then color and textural features were extracted as original features and statistics method was used to analyze the features. Maximum classification distance was used to analyze the main features obtained from image classification. At last， the classification ability of features was evaluated by Bayes discriminant analysis. Results Color and textural features were selected and classified. The correct classification rate of flower images was 85% and the correct classification rate of leaf images was 62%. The classification effect of flower images used by selected features was better than classification effect of original feature. Conclusion Compared with the classification of original features， the classification accuracy of flower medicine is higher through selected features. This research can lay a certain foundation for the further researches on Xinjiang Uyghur medicine images
　　and the improvement of feature extraction methods.
