+# ExamInk-Seg: Handwriting Trace Segmentation Dataset
+
+**ExamInk-Seg** 是一個專注於**手寫痕跡分割（Handwriting Segmentation）**的數據集。
+本數據集基於 SCUT-EnsExam 構建並進行了變種處理，旨在訓練模型精確地從試卷背景中提取或生成手寫筆跡的 Mask（掩膜）。
+
+適用於以下任務：
+*   **手寫痕跡提取**：將手寫內容與背景分離。
+*   **試卷去手寫（Erasure）**：配合 Mask 進行更精準的圖像修復。
+*   **數據增強**：提取手寫筆跡以合成到新的試卷背景中。
+
+## 📂 文件結構 (File Structure)
+
+數據集包含成對的 `source`（原圖）、`mask`（筆跡掩膜）以及 `target`（去手寫後的真值圖）。
+
+```text

+    mask/     # 目標：手寫痕跡的二值化 Mask (.jpg/png, 白色為筆跡，黑色為背景)
