Message Bus Integration

Input Topics (Subscriptions):

- user/input/multimodal        # Image + text input from user
- conversation/context/current # Current conversation state
- emotion/recognition/visual   # Visual emotion detection requests
- avatar/scene/analysis        # Scene understanding for avatar context

Output Topics (Publications):

- vision/analysis/complete     # Structured visual analysis results
- vision/context/emotional     # Emotional context from visual analysis
- vision/objects/detected      # Object detection and spatial information
- vision/text/extracted        # OCR and document parsing results

Binary Data Transport: Images and large binary payloads are transported through the ZeroMQ message bus using Protocol Buffers' bytes field type:

message MultimodalInput {
  string text_query = 1;
  bytes image_data = 2;          // Base64 or raw binary image data
  string image_format = 3;       // "jpeg", "png", "webp"
  MessageMetadata metadata = 4;
}

Large Payload Optimization: - Compression: Images compressed before transport (JPEG/WebP) - Chunking: Large files split into multiple messages if needed - Reference Pattern: For very large files, store locally and pass file paths - Memory Management: Images processed in streaming fashion to minimize RAM usage

Processing Pipeline

1. Image Preprocessing Component

    def __init__(self, message_bus):
        self.bus = message_bus
        self.llama_vision = LlamaVisionModel()  # Primary model
        self.qwen_vision = QwenVisionModel()    # Specialized tasks

        # Subscribe to multimodal input
        self.bus.subscribe("user.input.multimodal", self.on_multimodal_input)

    def on_multimodal_input(self, message):
        image_data = message['image']
        text_query = message['text']
        context = message.get('context', {})

        # Route to appropriate model based on task type
        if self.is_precision_task(text_query):
            result = self.process_with_qwen(image_data, text_query)
        else:
            result = self.process_with_llama(image_data, text_query)

        self.publish_analysis_results(result, context)

        "scene_description": vision_result.get('description'),
        "emotional_indicators": self.extract_emotional_cues(vision_result),
        "objects_present": vision_result.get('objects', []),

        "emotional_indicators": visual_context["emotional_indicators"],
        "social_context": visual_context["social_context"]
    })
