"Brain MRI Dataset for Glioma, Meningioma, and Pituitary Tumor Classification"

"This dataset contains a comprehensive collection of 7,023 brain MRI images, curated for the task of multi-class brain tumor classification. The images are categorized into four distinct classes: glioma, meningioma, pituitary tumor, and no tumor.To facilitate standardized model training and evaluation, the dataset is pre-organized into two primary directories: a Training set containing 5,712 images and a Testing set with 1,311 images. Within each directory, the images are further sorted into subdirectories, each named according to its respective class. All images are provided in JPEG format and have been resized to a uniform resolution of 128x128 pixels.This dataset provides a valuable resource for researchers and practitioners in the fields of medical imaging and machine learning, enabling the development, training, and benchmarking of robust algorithms for automated brain tumor detection and classification."
