dc.description.abstract在結合獨立成份分析(ICA)與支援向量機(SVM)於核磁共振影像(MRI)上,我們對分類的結果有不錯的表現。我們為了更進一步加速收集MR影像以統計不同疾病造成的腦體積容量的改變,我們使用Matlab 來發展具實用性的圖型使用者軟體介面來幫助臨床醫學的研究,我們所發展的程式也包含了一些影像處裡工具,和一些輔助性的演算法,例如分水嶺演算法等等,再日後希望進一步增加有用的處理工具,以方便今後的研究與臨床醫學有關的用途。這篇論文也探討SVM參數部份,我們知道參數的選擇對支援向量機的結果有很大的影響, 我們將會研究比較參數在ICA加上SVM和SVM的結果,最後我們會得知使用ICA做前處理後,假如SVM參數在一個合理範圍值,我們可以不用在意SVM參數的選擇,而可以得到不錯的分類結果。zh_TW
dc.description.abstractUsing independent component analysis (ICA), combining with support vector machines (SVM), in magnetic resonance imaging (MRI) analysis shows good performance. Different disease can have different effect on the brain volume change which can be detected by carefully exam the brain MR image. In order to increase the collection speed we have developed an useful GUI software for clinical research purpose. We also carefully examined the parameters of SVM, The parameters has great influence on the results of SVM. We have studied and compared the result of ICA plus SVM and SVM only. We can conclude that the MR image pass through the ICA process then SVM for classification could lead better result without worry about the selection for SVM parameteren_US
