+# This is the official datasets for the paper: FaceMe: Robust Blind Face Restoration With Personal Identification
+
+
+## Dataset Overview
+
+This repository contains the following five datasets:
+
+1. **FFHQ**
+2. **FFHQRef**
+3. **LFW-Test-Ref**
+4. **Wider-Test-Ref**
+5. **WebPhoto-Test-Ref**
+
+### Dataset Usage
+
+- **FFHQ** and **FFHQRef**: Used for training.
+- **LFW-Test-Ref**, **Wider-Test-Ref**, and **WebPhoto-Test-Ref**: Used for inference.
+
+### Important Notes
+
+Due to the large size of the **FFHQRef** dataset, it has been split into multiple parts. Before using this dataset, you need to merge the split files into a single `.tar` file and then extract it.
+
+#### Steps to Merge the Split Files
+
+Run the following command to merge all parts into a single file:
+
+```bash
+ls FFHQRef_part_*.tar | sort -V | xargs cat > merged_FFHQRef.tar
+```
+
+After merging, extract the merged_FFHQRef.tar file to access the dataset:
+
+```bash
+tar -xvf merged_FFHQRef.tar
+```
