# Image Studio Face Swap - Implementation Plan
|
||||
|
||||
**Date**: Current Session
|
||||
**Status**: ✅ **COMPLETE** - Backend & Frontend Implemented
|
||||
**Priority**: ⭐ **HIGH PRIORITY** - **COMPLETED**
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
Implement Face Swap Studio for Image Studio, following the same reusable architecture pattern as Editing feature.
|
||||
|
||||
**Models Integrated** (4 models): ✅ **COMPLETE**
|
||||
1. ✅ **Image Face Swap Pro** ($0.025) - Enhanced quality, realistic blending
|
||||
2. ✅ **Image Head Swap** ($0.025) - Full head replacement (face + hair + outline)
|
||||
3. ✅ **Akool Image Face Swap** ($0.16) - Multi-face swapping (up to 5 faces)
|
||||
4. ✅ **InfiniteYou** ($0.03) - High-quality identity preservation (ByteDance zero-shot)
|
||||
|
||||
---
|
||||
|
||||
## 🏗️ Architecture (REUSES EXISTING PATTERNS)
|
||||
|
||||
### **Phase 1: Foundation** (Same as Editing)
|
||||
|
||||
1. **Protocol & Options**
|
||||
- Create `FaceSwapOptions` dataclass in `base.py`
|
||||
- Create `FaceSwapProvider` protocol
|
||||
- Follow same pattern as `ImageEditProvider`
|
||||
|
||||
2. **Unified Entry Point**
|
||||
- Add `generate_face_swap()` to `main_image_generation.py`
|
||||
- **REUSE**: `_validate_image_operation()` helper
|
||||
- **REUSE**: `_track_image_operation_usage()` helper
|
||||
- Follow same pattern as `generate_image_edit()`
|
||||
|
||||
3. **Provider Implementation**
|
||||
- Create `WaveSpeedFaceSwapProvider` in `wavespeed_face_swap_provider.py`
|
||||
- **REUSE**: `WaveSpeedClient` for API calls
|
||||
- **REUSE**: Polling and download patterns from editing
|
||||

## 📋 Implementation Steps
|
||||
|
||||
### **Step 1: Protocol & Options** ✅ **COMPLETE**
|
||||
|
||||
**File**: `backend/services/llm_providers/image_generation/base.py`
|
||||
|
||||
**Added**:
|
||||
```python
|
||||
@dataclass
|
||||
class FaceSwapOptions:
|
||||
base_image_base64: str # Image to swap face into
|
||||
face_image_base64: str # Face to swap
|
||||
model: Optional[str] = None
|
||||
target_face_index: Optional[int] = None # For multi-face images
|
||||
target_gender: Optional[str] = None # "all", "female", "male"
|
||||
extra: Optional[Dict[str, Any]] = None
|
||||
|
||||
class FaceSwapProvider(Protocol):
|
||||
def swap_face(self, options: FaceSwapOptions) -> ImageGenerationResult:
|
||||
...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### **Step 2: WaveSpeedFaceSwapProvider Structure** ✅ **COMPLETE**
|
||||
|
||||
**File**: `backend/services/llm_providers/image_generation/wavespeed_face_swap_provider.py`
|
||||
|
||||
**Created**:
|
||||
- `SUPPORTED_MODELS` dict with 5 models
|
||||
- `_validate_options()` method
|
||||
- `_call_wavespeed_face_swap_api()` method
|
||||
- Helper methods: `get_available_models()`, `get_models_by_tier()`
|
||||
|
||||
---
|
||||
|
||||
### **Step 3: Unified Entry Point** ✅ **COMPLETE**
|
||||
|
||||
**File**: `backend/services/llm_providers/main_image_generation.py`
|
||||
|
||||
**Added**:
|
||||
```python
|
||||
def generate_face_swap(
|
||||
base_image_base64: str,
|
||||
face_image_base64: str,
|
||||
model: Optional[str] = None,
|
||||
options: Optional[Dict[str, Any]] = None,
|
||||
user_id: Optional[str] = None
|
||||
) -> ImageGenerationResult:
|
||||
# 1. REUSE: Validation helper
|
||||
_validate_image_operation(...)
|
||||
|
||||
# 2. Get provider
|
||||
provider = _get_face_swap_provider("wavespeed")
|
||||
|
||||
# 3. Prepare options
|
||||
face_swap_options = FaceSwapOptions(...)
|
||||
|
||||
# 4. Swap face
|
||||
result = provider.swap_face(face_swap_options)
|
||||
|
||||
# 5. REUSE: Tracking helper
|
||||
if user_id and result and result.image_bytes:
|
||||
_track_image_operation_usage(...)
|
||||
|
||||
return result
|
||||
```
|
||||
|
||||

|
||||
|
||||
### **Step 4: Service Layer** ✅ **COMPLETE**
|
||||
|
||||
**File**: `backend/services/image_studio/face_swap_service.py` ✅ **CREATED**
|
||||
|
||||
**Created**:
|
||||
```python
|
||||
class FaceSwapService:
|
||||
async def process_face_swap(
|
||||
self,
|
||||
request: FaceSwapRequest,
|
||||
user_id: Optional[str] = None
|
||||
) -> Dict[str, Any]:
|
||||
# Use unified entry point
|
||||
result = generate_face_swap(...)
|
||||
# Return normalized response
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### **Step 5: API Endpoint** ✅ **COMPLETE**
|
||||
|
||||
**File**: `backend/routers/image_studio.py`
|
||||
|
||||
**Added**:
|
||||
```python
|
||||
@router.post("/face-swap/process")
|
||||
async def process_face_swap(
|
||||
request: FaceSwapRequest,
|
||||
current_user: Dict[str, Any] = Depends(get_current_user),
|
||||
) -> FaceSwapResponse:
|
||||
# Call service
|
||||
```
|
||||
|
||||

||||
### **Step 6: Frontend** ✅ **COMPLETE**
