Brain Cancer 4-Class Image Dataset
Overview
This dataset contains MRI images for classifying brain tumors across four categories: glioma, meningioma, pituitary tumor, and no tumor. Each image is stored as an individual .png file, and the dataset is structured to be compatible with Lumina AI's Random Contrast Learning (RCL) algorithm via the PrismRCL application.
Dataset Structure
The dataset is organized into the following structure:
brain-cancer-4class/
train/
glioma_tumor/
image_001.png
image_002.png
...
meningioma_tumor/
image_001.png
image_002.png
...
pituitary_tumor/
image_001.png
image_002.png
...
no_tumor/
image_001.png
image_002.png
...
test/
glioma_tumor/
image_001.png
image_002.png
...
meningioma_tumor/
image_001.png
image_002.png
...
pituitary_tumor/
image_001.png
image_002.png
...
no_tumor/
image_001.png
image_002.png
...
Note: All file names must be unique across class folders. Only
.pngformat is supported by PrismRCL for image inputs.
Features
- Image Data: Each file contains a brain MRI scan in
.pngformat. - Classes: Four folders represent the classification targets:
glioma_tumormeningioma_tumorpituitary_tumorno_tumor
Usage (pre-split; optimal parameters)
Here is an example of how to load the dataset using PrismRCL:
C:\PrismRCL\PrismRCL.exe chisquared rclticks=10 boxdown=0 ^
data=C:\path\to\brain-cancer-4class\train testdata=C:\path\to\brain-cancer-4class\test ^
savemodel=C:\path\to\models\brain_cancer_4class.classify ^
log=C:\path\to\log_files stopwhendone
Explanation of Command:
- C:\PrismRCL\PrismRCL.exe: Path to the PrismRCL executable for classification
- chisquared: Specifies Chi-squared as the training evaluation method
- rclticks=10: Number of RCL iterations during training
- boxdown=0: RCL training parameter
- data=C:\path\to\brain-cancer-4class\train: Path to the training dataset
- testdata=C:\path\to\brain-cancer-4class\test: Path to the testing dataset
- savemodel=C:\path\to\models\brain_cancer_4class.classify: Output path for the trained model
- log=C:\path\to\log_files: Log file storage directory
- stopwhendone: Ends the session when training is complete
