# BrainTumorClassification
A large-scale curated brain MRI image dataset for multi-class brain tumor classification and medical imaging research.
## Dataset Overview
**BrainTumorClassification** is a curated collection of **16,599 brain MRI images** designed for training and evaluating machine learning and deep learning models for brain tumor classification.
The dataset contains four diagnostic categories:
* Glioma
* Meningioma
* Pituitary Tumor
* No Tumor
This dataset was developed through the curation, validation, and reorganization of publicly available Brain Tumor MRI datasets, primarily derived from widely used Kaggle sources. Additional quality checks, data verification, and structural improvements were performed to create a larger and more accessible resource for the research community.
## Dataset Structure
```text
BrainTumorClassification/
│
├── train/
│ ├── _classes.csv
│ ├── part1/
│ │ └── MRI images
│ │
│ └── part2/
│ └── MRI images

```
### Train Split
The training split contains the majority of images and is divided into `part1` and `part2` directories. Both folders contain MRI images used for model training, while `_classes.csv` stores the corresponding label information.
### Validation Split
The validation split contains MRI images used for model selection, hyperparameter tuning, and performance monitoring during training. Labels are provided through the accompanying `_classes.csv` file.
### Test Split
The test split contains MRI images reserved for final evaluation and benchmarking. Labels are provided through the corresponding `_classes.csv` file.

## Data Curation
This dataset was created through a structured curation pipeline that included:
* Collection from publicly available Brain Tumor MRI datasets.
* Verification of image-label consistency.
* Removal of corrupted or unusable files.
* Reorganization into a standardized directory structure.
* Quality validation and dataset cleaning.
* Preparation for machine learning and deep learning workflows.
The goal of this effort was to provide a larger, cleaner, and easier-to-use dataset for researchers, students, and practitioners working on medical image classification.
