+# Quick Task 260330-mb3: 完整人脸识别示例
+
+**Date:** 2026-03-30
+**Commit:** 3c7e992
+
+## Summary
+
+重写 example 示例代码，实现真正的 1:1 人脸识别功能。
+
+## Changes
+
+### example/lib/main.dart
+- 完全重写 `FaceRecognitionScreen` 类
+- 实现 `_registerFace()` 方法：使用 `extractFaceFeature(extractType: 0)` 注册模式
+- 实现 `_verifyFace()` 方法：使用 `extractFaceFeature(extractType: 1)` + `compareFaceFeature()`
+- 使用 `SharedPreferences` 存储人脸特征数据 (Base64 编码)
+- 添加注册/验证模式切换功能
+- 显示相似度百分比和验证结果
+
+### example/pubspec.yaml
+- 添加 `shared_preferences: ^2.2.2` 依赖
+
+## Key API Usage
+
+| 流程 | API | 参数 |
+|------|-----|------|
+| 人脸检测 | `detectFaces()` | format=2050 (NV21) |
+| 注册特征提取 | `extractFaceFeature()` | extractType=0 (REGISTER) |
+| 识别特征提取 | `extractFaceFeature()` | extractType=1 (RECOGNIZE) |
+| 特征比对 | `compareFaceFeature()` | compareModel=0 (LIFE_PHOTO) |
+
+## Verification Threshold
+
+- 推荐阈值: 0.8 (生活照)
+- 相似度 >= 0.8 判定为同一人
+
+## Files Modified
+
+- `example/lib/main.dart` (+419/-208 lines)
+- `example/pubspec.yaml` (+3 lines)
