## Overview

**E-SCDD** is an extended electroluminescence (EL) imagery dataset for photovoltaic (PV) module analysis.  
It expands the existing [BenchmarkELimages](https://github.com/TheMakiran/BenchmarkELimages) dataset by adding additional EL samples,
refined pixel-level annotations, and standardized splits to support research on:

- defect detection  
- anomaly segmentation  
- robustness evaluation  
- generative modeling  
- PV modules' health monitoring and maintenance  

## Dataset Structure

- Images: EL imagery of PV modules, including multiple defect types such as cracks and inactive regions.

- Annotations: pixel-level segmentation masks provided in indexed PNG format.

- Splits: train, validation, and test folders following the original schema

## Citation
This dataset extends and builds upon the [BenchmarkELimages](https://github.com/TheMakiran/BenchmarkELimages) dataset, 
originally released under the MIT License.
