const app = express(); const server = http.createServer(app); const io = socketIO(server, { cors: { origin: process.env.CLIENT_URL || 'http://localhost:3000', methods: ['GET', 'POST'] } });

// Middleware app.use(cors()); app.use(express.json()); app.use(express.urlencoded({ extended: true }));

// AI Processing Service const { processFrame } = require('./services/aiService');

const PORT = process.env.PORT || 5000; server.listen(PORT, () => { console.log(`Server running on port ${PORT}`); }); ```

### server/models/Ad.js ```javascript const mongoose = require('mongoose');

const adSchema = new mongoose.Schema({ brandName: { type: String, required: true }, category: { type: String, enum: ['food', 'sports', 'electronics', 'apparel', 'beverages'], required: true }, imageUrl: { type: String, required: true }, targetSurfaces: [{ type: String, enum: ['boundary', 'pitch', 'stadium', 'player', 'scoreboard'] }], priority: { type: Number, default: 1 }, active: { type: Boolean, default: true }, metadata: { colorScheme: String, dimensions: { width: Number, height: Number }, opacity: Number }, createdAt: { type: Date, default: Date.now } });

module.exports = mongoose.model('Ad', adSchema); ```

let model = null;

// Initialize the detection model async function initializeModel() { try { model = await cocoSsd.load(); console.log('AI model loaded successfully'); } catch (error) { console.error('Error loading AI model:', error); } }

### server/routes/broadcasts.js ```javascript const express = require('express'); const router = express.Router(); const Broadcast = require('../models/Broadcast'); const { processFrame } = require('../services/aiService');

// Get all broadcasts router.get('/', async (req, res) => { try { const broadcasts = await Broadcast.find().sort({ date: -1 }); res.json(broadcasts); } catch (error) { res.status(500).json({ error: error.message }); } });

// Create new broadcast router.post('/', async (req, res) => { try { const broadcast = new Broadcast(req.body); await broadcast.save(); res.status(201).json(broadcast); } catch (error) { res.status(400).json({ error: error.message }); } });

class SurfaceDetector: def __init__(self, model_path): self.model = tf.saved_model.load(model_path) self.category_index = label_map_util.create_category_index_from_labelmap( 'label_map.pbtxt', use_display_name=True ) def detect_surfaces(self, frame): """ Detect suitable surfaces for ad placement in IPL broadcast frames """ input_tensor = tf.convert_to_tensor(frame) input_tensor = input_tensor[tf.newaxis, ...] detections = self.model(input_tensor) surfaces = [] for detection in detections['detection_boxes'][0]: # Filter for suitable surfaces if detection[4] > 0.5: # Confidence threshold surfaces.append({ 'bbox': detection[:4].numpy(), 'confidence': detection[4].numpy(), 'class': self.category_index[detection[5].numpy()]['name'] }) return surfaces def optimize_placement(self, surfaces, ad_dimensions): """ Optimize ad placement positions to maximize visibility """ # Implement placement optimization algorithm pass ```

## Deployment Configuration

### docker-compose.yml ```yaml version: '3.8'
