Here are a few options: This project classifies brain MRI images into two categories: normal and abnormal. Many scans were collected from each participant at intervals between 2 weeks Two different datasets were used in this work - the pathological brain images were obtained from the Brain Tumour Segmentation (BraTS) 2019 dataset, which includes images Despite being an emerging field, a simple internet search for open MRI datasets presents an overwhelming number of results. Many scans were collected The common anomaly in brain include glioblastomas, multiple sclerosis (MS), cerebral infarction (CI) and so forth. This project classifies brain MRIs as normal or abnormal using four approaches: CNNs, histogram features, SVMs, and custom ResNet models.
