# 模糊臉部與隱私資訊 {#face-pii-blur}
使用 AI 驅動的臉部偵測(MediaPipe)自動偵測並模糊影像中的臉部。
## API Endpoint {#api-endpoint}
`POST /api/v1/tools/image/blur-faces`
**處理方式:** 非同步(回傳 202,透過 SSE 輪詢 `/api/v1/jobs/{jobId}/progress` 取得狀態)
**模型套件:** `face-detection`200-300 MB
## Parameters {#parameters}
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| file | file | Yes | - | 影像檔案(multipart |
| blurRadius | number | No | `30` | 套用於偵測到臉部的模糊半徑(1-100) |
| sensitivity | number | No | `0.5` | 臉部偵測靈敏度(0-1)。較低的值以較高的信心偵測較少的臉部 |
## Example Request {#example-request}
```bash
curl -X POST http://localhost:1349/api/v1/tools/image/blur-faces \
-F "file=@group-photo.jpg" \
-F 'settings={"blurRadius":40,"sensitivity":0.3}'
```
## Response {#response}
### Initial Response (202 Accepted) {#initial-response-202-accepted}
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"async": true
}
```
### Progress (SSE at `/api/v1/jobs/{jobId}/progress`) {#progress-sse-at-api-v1-jobs-jobid-progress}
```
event: progress
data: {"phase":"processing","stage":"Detecting faces...","percent":40}
```
### Final Result (via SSE) {#final-result-via-sse}
```json
{
"phase": "complete",
"percent": 100,
"result": {
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/{jobId}/group-photo_blurred.jpg",
"originalSize": 450000,
"processedSize": 420000,
"facesDetected": 3,
"faces": [
{"x": 100, "y": 50, "w": 80, "h": 80},
{"x": 300, "y": 60, "w": 75, "h": 75},
{"x": 500, "y": 55, "w": 85, "h": 85}
]
}
}
```
### No Faces Detected {#no-faces-detected}
若未找到臉部,結果會包含一則警告:
```json
{
"phase": "complete",
"percent": 100,
"result": {
"facesDetected": 0,
"warning": "No faces detected in this image. Try increasing detection sensitivity."
}
}
```
## Notes {#notes}
- 需要安裝 `face-detection` 模型套件(200-300 MB)。
- 輸出格式會自動與輸入格式相符。
- `faces` 陣列包含每個偵測到臉部的邊界框座標(x、y、width、height)。
- 增加 `sensitivity`(越接近 1.0)以偵測更多臉部,包含部分被遮擋的臉部。
- 透過自動解碼支援 HEIC/HEIF、RAW、TGA、PSD、EXR 及 HDR 輸入格式。
