| # OLDA-Bench Dataset |
|
|
| ## Overview |
|
|
| OLDA-Bench is a benchmark dataset for oral leukoplakia progression analysis. The dataset contains oral photographic images with lesion annotations, covering oral leukoplakia and oral leukoplakia-associated cancer lesions. |
|
|
| The dataset is designed to support: |
|
|
| * Oral lesion detection |
| * Instance segmentation |
| * Progression recognition |
| * Clinical validation studies |
