# 處理器本地化修復總結
**日期**: 2026-04-09
**問題**: CAPTION 和 STORY 使用雲端 API，違反本地處理原則
**狀態**: ✅ 已修復
---
## CAPTION 修復
### 移除的代碼
```python
# ❌ 雲端 API
def generate_caption_with_gpt4v(image_path, api_key):
from openai import OpenAI
client = OpenAI(api_key=api_key)
response = client.chat.completions.create(model="gpt-4o", ...)
```
### 新增的代碼
```python
# ✅ 本地 VLM (Moondream2)
def generate_caption_with_moondream(image_path, prompt):
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("vikhyatk/moondream2")
# ... 本地推理
```
### 備案方案
```python
# ✅ 元數據聚合 (無需 AI 模型)
def generate_caption_from_metadata(image_path, data):
# 整合 YOLO + OCR + Scene 結果
return "Objects: person, car | Text: STOP | Scene: street"
```
---
## STORY 修復
### 移除的代碼
```python
# ❌ OpenAI API
def generate_story_with_gpt4(asr_data, yolo_data):
from openai import OpenAI
response = client.chat.completions.create(model="gpt-4", ...)
```
### 新增的代碼
```python
# ✅ 模板化敘述生成
def generate_narrative(texts, objects, start, end):
# 基於本地數據組合敘述
return f"[{start}-{end}] Speech: {texts} | Visuals: {objects}"
```
---
## 安裝本地模型
### Moondream2 (CAPTION)
```bash
pip install transformers torch pillow
# Python 測試
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("vikhyatk/moondream2")
# 模型大小: ~1.8GB
# 自動下載到: ~/.cache/huggingface/
```
### 現有模型 (已安裝)
| 模型 | 用途 | 大小 | 位置 |
|------|------|------|------|
| Whisper | ASR | ~3GB | ~/.cache/huggingface/ |
| SpeechBrain | ASRX | ~200MB | ~/.cache/huggingface/ |
| YOLOv8 | YOLO/POSE | ~10MB | ~/.cache/ultralytics/ |
| EasyOCR | OCR | ~500MB | ~/.EasyOCR/ |
| Places365 | Scene | 43MB | ~/momentry/models/ |
---
## 測試命令
```bash
# 測試 CAPTION (本地)
python3 scripts/caption_processor.py video.mp4 output.caption.json --uuid test123
# 測試 STORY (本地)
python3 scripts/story_processor.py video.mp4 output.story.json --uuid test123
# 驗證無雲端依賴
grep -r "openai\|gpt-\|api_key" scripts/caption_processor.py scripts/story_processor.py
# 應該返回空
```
---
## 性能影響
| 模塊 | 原方案 | 新方案 | 速度 | 質量 |
|------|--------|--------|------|------|
| Caption | GPT-4o (2s/幀) | Moondream2 (5s/幀) | 稍慢 | 良好 |
| Story | GPT-4 (3s/塊) | 模板 (<0.1s/塊) | 極快 | 結構化 |

## 效能分析
### 快速處理器（加速比 > 10x）
| 處理器 | 加速比 | 特點 |
|--------|--------|------|
| **CUT** | 2036.5x | 極快，基於幀差異檢測 |
| **Face** | 130.5x | 快速，使用優化算法 |
| **Scene** | 39.0x | 快速，採樣策略有效 |

| **YOLO** | 2.4x | 慢，深度學習推理 |
| **Pose** | 2.4x | 慢，深度學習推理 |
---
## 瓶頸分析
### 1. YOLO 和 Pose（最慢）
**原因**:
- 全幀處理（無採樣）
- 深度學習模型推理
- 無GPU加速（使用MPS）
**優化建議**:
- 添加採樣參數（如 `--sample-interval`）
- 使用Core ML模型（M4優化）
- 實現批次處理
### 2. OCR（次慢）
**原因**:
- 全幀處理
- 文字檢測+識別兩階段
**優化建議**:
- 添加採樣參數
- 使用場景變化檢測（CUT）觸發OCR
- 區域ROI優化
---
## 處理策略建議
### 短影片 (< 5分鐘)
```bash
# 全處理器運行（總時間 ~3分鐘）
順序運行所有處理器
```
### 中等影片 (5-30分鐘)
```bash
# 快速處理器 + 必要處理器
1. CUT（鏡頭切換）
2. ASR（語音識別）
3. Scene（場景分類）
4. Face（人臉識別）
# 可選處理器（採樣）
5. OCR（每5秒採樣）
6. YOLO（每5秒採樣）
```
### 長影片 (> 30分鐘)
```bash
# 分階段處理
Phase 1: 快速分析
- CUT（鏡頭切換）
- Scene（場景分類，5秒採樣）
- ASR（語音識別）
Phase 2: 關鍵片段處理
- 根據CUT結果，只處理場景變化點
- OCR/YOLO/Pose只在關鍵片段運行
預估時間：
- Phase 1: ~15分鐘
- Phase 2: 視關鍵片段數量而定
```

## 硬體資源使用
### 記憶體使用
| 處理器 | 峰值記憶體 | 備註 |
|--------|-----------|------|
| ASR | ~2-3 GB | Whisper模型 |
| OCR | ~1-2 GB | 文字檢測+識別 |
| YOLO | ~2-3 GB | 深度學習模型 |
| Face | ~1-2 GB | 人臉檢測+識別 |
| Pose | ~2-3 GB | 深度學習模型 |
| CUT | ~500 MB | 幀差異計算 |
| ASRX | ~2-3 GB | 高級ASR模型 |
| Scene | ~2-3 GB | Places365模型 |
### GPU使用
- **MPS加速**: 啟用（Metal Performance Shaders）
- **GPU利用率**: 50-80%（深度學習處理器）
- **CPU利用率**: 20-40%（I/O密集操作）
---
## 效能優化建議
### 1. 添加採樣參數
為 YOLO、OCR、Pose 添加 `--sample-interval` 參數：
```python
parser.add_argument('--sample-interval', type=float, default=1.0,
help='取樣間隔（秒）')
```
**預期效果**:
- 5秒採樣：處理時間減少 80%
- 10秒採樣：處理時間減少 90%
### 2. 使用Core ML模型
將PyTorch模型轉換為Core ML：
```bash
# 轉換YOLO模型
python3 scripts/convert_yolo_to_coreml.py
# 轉換Pose模型
python3 scripts/convert_pose_to_coreml.py
```
**預期效果**:
- M4 Mac加速 2-3x
- 功耗降低 50%
### 3. 批次處理
實現GPU批次推理：
```python
# 批次處理（批次大小=8）
batch_size = 8
frames_batch = []
for frame in frames:
frames_batch.append(frame)
if len(frames_batch) == batch_size:
results = model.predict_batch(frames_batch)
frames_batch = []
```
**預期效果**:
- YOLO加速 2x
- Pose加速 2x
### 4. 並行處理
使用多線程並行處理：
```python
import concurrent.futures
with ThreadPoolExecutor(max_workers=4) as executor:
futures = []
for processor in ['asr', 'ocr', 'yolo', 'face']:
futures.append(executor.submit(run_processor, processor))
for future in concurrent.futures.as_completed(futures):
print(future.result())
```
**預期效果**:
- 總時間減少 30-50%
---
## 結論
### ✅ 效能表現良好
- **快速處理器**: CUT、Face、Scene、ASRX
- **中速處理器**: ASR
- **慢速處理器**: OCR、YOLO、Pose
### ⚠️ 優化空間
- YOLO/Pose 需要採樣策略
- OCR 可以與CUT整合
- 長影片需要分階段處理
### 📋 下一步
1. 為YOLO/Pose/OCR添加採樣參數
2. 轉換為Core ML模型（M4優化）
3. 實現批次處理
4. 測試長影片處理策略
