Business Logic Specification
Overview
AI StyleGallery is a web application that enables users to transform their uploaded images using various AI-generated artistic styles through integration with external AI services.
Core Business Requirements
Primary User Journey
- Image Upload: Users can upload personal images to their gallery
- Style Selection: Users can browse and select from available AI artistic styles
- AI Processing: Selected images are sent to external AI services for style transformation
- Result Management: Users can view styled results and choose to keep (make permanent) or discard them
- Gallery Management: Users can view their collection of original and styled images
Key Business Rules
- Image Privacy: Images are private by default, users control visibility
- Temporary Processing: AI-styled images are initially temporary until user confirms
- Style Availability: Only enabled styles from active AI models are available to users
- Provider Flexibility: Support multiple AI service providers (ComfyUI, RunwareAI, etc.)
- Real-time Progress: Users receive real-time updates during AI processing
Core Business Workflows
1. Image Style Transformation Workflow
Process Flow
User selects image → Opens context menu → Chooses "Change Style" →
Browses style selector → Selects style → Initiates AI processing →
Receives real-time progress updates → Views styled result →
Chooses to keep or discard the styled image
Technical Implementation
- Frontend captures user selection via Vue.js components
- Backend validates request and loads appropriate AI plugin
- Plugin handles communication with external AI service
- Real-time progress tracked via WebSocket (ComfyUI) or polling (other providers)
- Styled image saved to storage and database record created
- User notified of completion and can manage result
Success Criteria
- Processing completes within reasonable time (typically 30-180 seconds)
- User receives clear progress feedback during processing
- Styled image maintains acceptable quality and resolution
- User can easily keep or discard results
2. Gallery Management Workflow
Image Synchronization
- Automatic sync between filesystem and database
- Missing files removed from database
- New files added to database with metadata
- Maintains data consistency across application restarts
Visibility Rules
- Public Images: Visible to all users
- Private Images: Only visible to image owner
- Temporary Images: Visible to owner during processing/review period
- Authenticated Users: See all their own images
- Unauthenticated Users: See only public images and their temporary results
3. Admin Management Workflow
Content Management
- Styles: Create, edit, enable/disable artistic styles
- AI Models: Configure available AI models and their parameters
- API Providers: Set up connections to external AI services
- Users: Manage user accounts and assign roles
- Settings: Configure application-wide settings
Quality Assurance
- Preview images for styles before publishing
- Test connections to AI services
- Monitor processing success rates
- Manage storage and cleanup old temporary files
Business Entities & Relationships
Primary Entities
- Users: Account holders with roles and preferences
- Images: Uploaded files with metadata and processing status
- Styles: AI artistic styles with prompts and parameters
- AI Models: Specific AI models (e.g., Stable Diffusion variants)
- API Providers: External AI services (ComfyUI, RunwareAI, etc.)
Key Relationships
- User → Images: One-to-many (users own multiple images)
- Image → Style: Many-to-one (multiple images can use same style)
- Style → AI Model: Many-to-one (multiple styles can use same model)
- AI Model → API Provider: Many-to-one (multiple models can use same provider)
- Image → Original Image: Self-referencing (styled images reference originals)
Business Constraints & Validation Rules
Data Validation
- Image Files: Must be valid image formats (JPEG, PNG, WebP), max 10MB
- Style Prompts: Required text describing desired artistic transformation
- API URLs: Must be valid, accessible endpoints
- User Email: Must be unique and valid format
Business Rules
- Temporary Image Expiry: Styled images expire if not kept within timeframe
- Storage Limits: Maximum storage per user or globally
- API Rate Limits: Respect external service limitations
- Processing Queue: Handle multiple simultaneous requests appropriately
Success Metrics
User Experience
- Processing Speed: Average time under 60 seconds for style transformation
- Success Rate: 95%+ successful transformations
- User Retention: Users return and process multiple images
- Feature Adoption: High usage of style transformation features
Technical Performance
- System Uptime: 99.5%+ availability
- Response Times: Gallery loads under 2 seconds
- Error Rates: Under 1% processing failures
- Storage Efficiency: Automatic cleanup of unused temporary files
Future Enhancement Opportunities
Potential Features
- Batch Processing: Apply styles to multiple images simultaneously
- Style Chaining: Apply multiple styles in sequence
- Custom Styles: User-created style presets
- Social Features: Share styled images with other users
- Advanced Filters: Search and filter gallery by style, date, etc.
- Mobile Optimization: Enhanced mobile experience
- API Access: Third-party integrations via API
Scalability Considerations
- Multiple AI Providers: Load balancing across providers
- CDN Integration: Faster image delivery globally
- Database Optimization: Handle large numbers of images efficiently
- Caching Strategy: Reduce redundant AI processing
