Development of computer-aided approach for brain tumor detection using random forest classifier

摘要

The nonlinear development of cells in brain region forms the abnormal patterns in brain in the form of tumors. It is necessary to detect and diagnose the brain tumors in an automated manner using computer-aided approaches at large population areas. The noises in brain magnetic resonance image is detected and reduced as preprocessing steps and then grey level co-occurrence matrix are now extracted from the preprocessed brain image. In this article, random forest classifier-based brain tumor detection and segmentation methodology is proposed to classify the brain image into normal or abnormal. The proposed brain tumor detection and segmentation system is analyzed in terms of sensitivity, specificity, false-positive rate, false-negative rate, likelihood ratio positive, and likelihood ratio negative.
