摘要
En 中文
Detection of brain tumor's grade is a very important task in treatment plan design which was done using invasive methods such as pathological examination. This examination needs resection procedure and resulted in pain, hemorrhage and infection. The aim of this study is to provide an automated non-invasive method for estimation of brain tumor's grade using Magnetic Resonance Images (MRI). After pre-processing, using Fuzzy C-Means (FCM) segmentation method, tumor region was extracted from post-processed images. In feature extraction, texture, Local Binary Pattern (LBP) and fractal-based features were extracted using Matlab software. Then using Grasshopper Optimization Algorithm (GOA), parameters of three different classification methods including Random Forest (RF), K-Nearest Neighbor (KNN) and Support Vector Machine (SVM) were optimized. Finally, performance of three applied classifiers before and after optimization were compared. The results showed that the random forest with accuracy of 99.09% has achieved better performance comparing other classification methods.
