System Architecture

Frontend Architecture

• Framework: Streamlit web application framework
• Layout: Wide layout with expandable sidebar for controls
• Caching Strategy: Uses Streamlit's @st.cache_resource and @st.cache_data decorators for model and utility caching
• Session Management: Streamlit session state for managing uploaded images and model loading status

Backend Architecture

• Core Framework: Python-based with modular utility classes
• Model Management: Centralized ModelManager class for loading and managing ML models
• Image Processing: Dedicated ImageProcessor class for applying various filters and transformations
• Visualization: Separate Visualizer class for rendering computer vision results

Modular Design

The application follows a clean separation of concerns with three main utility modules:

• utils/model_utils.py: ML model loading and inference
• utils/image_processing.py: Image filtering and processing operations
• utils/visualization.py: Result visualization and rendering

Key Components

ModelManager (utils/model_utils.py)

• Purpose: Manages loading and inference of multiple ML models
• Models Supported:
  • MobileNetV2 for image classification (ImageNet pretrained)
  • Placeholder architecture for object detection and segmentation models
• Preprocessing: Handles image preprocessing for different model requirements
• Output: Structured prediction results with confidence scores

ImageProcessor (utils/image_processing.py)

• Purpose: Applies various image filters and enhancements
• Supported Filters: Blur, Gaussian blur, sharpen, edge detection, emboss, brightness, contrast, saturation
• Architecture: Filter registry pattern with modular filter functions
• Error Handling: Graceful degradation when filters fail

Visualizer (utils/visualization.py)

• Purpose: Renders computer vision results with visual overlays
• Capabilities: Bounding box drawing, label rendering, confidence score display
• Color Management: Predefined color palette for consistent visualization
• Format Handling: Converts between PIL and OpenCV image formats

Data Flow

1. Image Input: User uploads image through Streamlit file uploader
2. Session Storage: Image stored in Streamlit session state
3. Model Inference: Selected models process the image through ModelManager
4. Result Processing: Raw predictions converted to structured results
5. Visualization: Results rendered with bounding boxes/labels via Visualizer
6. Display: Processed images and results displayed in Streamlit interface
