##  Quick Start

### Basic Usage

```python
from lisa import LISAModel
import torch

# Load the model - same initialization process
model = LISAModel.from_pretrained("./")
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)

# Process vision + audio input
result = model.process_multimodal(
    image_path="image.jpg",    # Visual input - what the model "sees"
    audio_path="audio.wav"     # Auditory input - what the model "hears"
)

print(result.response)
```

### Streaming Processing

```python
import cv2
import sounddevice as sd
import numpy as np
import threading
from queue import Queue

# Initialize LISA for multimodal streaming
lisa = LISAModel.from_pretrained("./")
lisa.start_streaming()

# Create synchronized queues for audio and video data
audio_queue = Queue(maxsize=10)  # Buffer for audio chunks
frame_queue = Queue(maxsize=5)   # Buffer for video frames

def audio_callback(indata, frames, time, status):
    """Continuously capture audio and store in queue"""
    if not audio_queue.full():
        audio_queue.put(indata.copy())  # Store audio chunk for processing

# Start audio stream (runs in background thread)
audio_stream = sd.InputStream(
    callback=audio_callback,
    channels=1,        # Mono audio for simplicity
    samplerate=16000,  # Standard rate for speech processing
    blocksize=1024     # Audio chunk size
)

# Process synchronized video and audio streams
cap = cv2.VideoCapture(0)
audio_stream.start()

while True:
    ret, frame = cap.read()
    if ret and not audio_queue.empty():
        # Get the most recent audio chunk
        audio_chunk = audio_queue.get()
        
        # Process both video frame AND audio together
        result = lisa.process_multimodal_frame(
            frame=frame,           # What the AI "sees" right now
            audio=audio_chunk      # What the AI "hears" right now
        )
        
        print(f"Vision: {result.visual_detections}")
        print(f"Audio: {result.audio_events}")
        print(f"Combined: {result.multimodal_inference}")
        
        # Display with annotations from both modalities
        annotated_frame = lisa.annotate_multimodal_frame(frame, result)
        cv2.imshow('LISA Vision+Audio', annotated_frame)
        
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

# Clean up resources
audio_stream.stop()
cap.release()
cv2.destroyAllWindows()
```

### Vision+Audio Processing

```python
import cv2
import numpy as np
from threading import Thread
import time

# Enhanced callback that processes both audio and synchronized video
def multimodal_callback(audio_chunk, current_frame=None):
    """
    This callback now processes both audio and visual information together.
    Think of this like how humans naturally combine what they hear with what they see
    to understand a conversation or situation more completely.
    """
    
    # Process both modalities together - this is the key difference
    result = lisa.process_multimodal_realtime(
        audio=audio_chunk,      # What the AI hears (speech, sounds, emotions)
        frame=current_frame     # What the AI sees (faces, gestures, environment)
    )
    
    # Now we get richer, cross-modal insights
    if result.transcript:
        print(f"Speech: {result.transcript}")
    
    # Emotion detection now uses BOTH audio tone AND facial expressions
    if result.emotion_scores:
        print(f"Voice Emotion: {result.audio_emotion}")      # From speech patterns
        print(f"Visual Emotion: {result.facial_emotion}")    # From facial expressions  
        print(f"Combined Emotion: {result.fused_emotion}")   # Best of both worlds
    
    # New capabilities emerge from combining modalities
    if result.speaker_identification:
        print(f"Speaker: {result.identified_speaker}")       # Match voice to face
    
    if result.attention_focus:
        print(f"Looking at: {result.visual_attention}")      # Where are they looking while speaking?

# Capture video frames continuously to sync with audio
current_frame = None
cap = cv2.VideoCapture(0)

def capture_frames():
    """
    Continuously capture video frames in a separate thread.
    This ensures we always have a recent frame available when audio arrives.
    Think of this as maintaining a 'visual memory' that stays current.
    """
    global current_frame
    while True:
        ret, frame = cap.read()
        if ret:
            current_frame = frame  # Update the most recent visual context
        time.sleep(0.03)  # Roughly 30 FPS capture rate

# Start the video capture thread
video_thread = Thread(target=capture_frames, daemon=True)
video_thread.start()

# Modified callback function that includes current visual context
def enhanced_audio_callback(audio_chunk):
    """
    This wrapper ensures each audio chunk is processed alongside
    the most recent visual frame, creating temporal alignment.
    """
    multimodal_callback(audio_chunk, current_frame)

# Start the integrated audio+vision stream
lisa.start_audio_stream(callback=enhanced_audio_callback)
```

- **Temporal Synchronization:** The biggest challenge in multimodal AI is ensuring that what you hear and what you see correspond to the same moment in time. Notice how we maintain a current_frame variable that's continuously updated in a separate thread. This creates a "visual memory" that's always fresh when new audio arrives. Think of it like how your brain automatically coordinates the timing of what your eyes see with what your ears hear.
- **Cross-Modal Enhancement:** The real magic happens in process_multimodal_realtime(). Instead of analyzing speech and visual cues separately, the model can now cross-reference them. For example, if someone says "I'm fine" but their facial expression shows distress, the combined emotion analysis will be more accurate than either modality alone. This mimics human intuition about reading people's true feelings.
- **Emergent Capabilities:** When you combine vision and audio, new possibilities emerge that weren't available with either modality alone. Speaker identification becomes much more robust when you can match a voice to a face. Understanding where someone is looking while they speak adds crucial context about their intent and focus.
- **Threaded Architecture:** Notice how we use a separate thread for video capture. This architectural choice is crucial because audio processing is time-sensitive - you cannot afford to miss audio chunks while waiting for a video frame to process. The threaded approach ensures smooth, real-time operation of both streams.
