Abstract: This study conducted a comprehensive analysis of online brain tumor scan data, developing and evaluating a robust model to discern Intracranial Neoplasm brain tumors. Employing an empirical approach, we utilized Mask-RCNN and U-net for segmenting Intracranial Neoplasm tumors from brain Magnetic Resonance Images (MRIs). Our methodology encompassed dataset elucidation, data pre-processing, network architecture, training, testing strategies, and proposed ensemble methods. The dataset comprising 253 brain tumors and employed U-nets and Mask-RCNN, utilizing a statistical confusion matrix to evaluate tumor stratification performance, differentiating true positives (Tp), true negatives (Tn), false positives (Fp), and false negatives (Fn). Employing deep learning techniques and Python programming, using Accuracy, Sensitivity, Specificity, Dice coefficient, and Jaccard index metrics. Our findings revealed that the 176-training brain tumor dataset samples, 95 identified as "yes" tumors, while 5 misclassified as "no" tumors. For the testing set comprising 77 cases, 42 "yes" tumors were identified, along with 26 "no" tumors. The training model achieved remarkable performance metrics, boasting 93% accuracy, 95% sensitivity, and 90% specificity, with a 96% similarity to ground truth. The testing set results showcased 89% sensitivity, 86% Specificity, and 88% accuracy, across 253 cases, our model demonstrated 92% sensitivity, 88% specificity, and 90.5% accuracy. The model's runtime for segmenting the 176 datasets was 466 seconds, approximately 7 minutes and 45 seconds. In conclusion, our study yields highly satisfactory results with an accuracy of 90.5%, 92% sensitivity, and 88% specificity. This model exhibits promising potential for precise brain tumor boundary detection, enhancing segmentation, diagnosis, and guiding brain tumor surgery.
