+# DocRes MBD Weights (mbd.pkl)
+
+These are the **MBD weights** (`mbd.pkl`) used by the **DocRes** model (CVPR 2024), rehosted for use in the [Doctra](https://github.com/your-username/doctra) library.

+
+## ✅ Intended Use
+The `mbd.pkl` weights are used for **Mask and Background Detection (MBD)**, a critical component of DocRes for:
+
+- Generating document masks  
+- Producing background priors  
+- Supporting the Dynamic Task-Specific Prompt (DTSPrompt) mechanism  
+
+These weights are required to prepare task-specific prompts for the main `docres.pkl` model.
+
+---
+
+## ⚠️ Limitations
+- Designed specifically for document mask/background detection.  
+- Performance depends on the quality of scanned/photographed inputs.  
+- Should be used in combination with the main DocRes weights (`docres.pkl`) for full restoration capability.
