The system employs deep learning techniques combining a VGG-16 pre-trained model and transfer learning to analyze MRI images and classify them into four categories — Glioma, Meningioma, Pituitary, and No Tumour — in real time. Features such as MRI image upload, automated feature extraction, confidence score generation, and a web-based diagnostic interface are integrated to enhance usability and clinical reliability. The system is designed with a modular architecture and a fine-tuned classification pipeline for efficient prediction management. It is observed that the proposed system improves diagnostic accuracy, reduces radiologist workload, and enhances early detection of life-threatening neurological conditions.
