This document presents a proposed method for automatic brain tumor tissue detection in T1-weighted MR images. The method uses a four-step process: segmentation, morphological operations, feature extraction, and classification. In the training section, MRI images are preprocessed and features are extracted using gray-level co-occurrence matrix (GLCM). The features are then used to train a classifier to detect and classify tumors as normal, abnormal, benign, or malignant. In the testing section, input MRI images also undergo preprocessing, feature extraction with GLCM, and then the trained classifier detects, segments, and classifies any tumor tissues found in the images. The goal is to automatically localize and diagnose brain tumor masses in MRI scans.
