All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

# Face / PII Blur {#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。
