What is Trash Classification AI?

The Trash Classification AI System is an intelligent waste management solution that combines computer vision, deep learning, and robotics to automatically identify and sort different types of trash. Built with YOLOv11 and PyTorch, it provides real-time object detection and segmentation capabilities for waste classification.

Problem Statement

Traditional waste sorting is manual, time-consuming, and error-prone. Recycling facilities need automated solutions that can:
  • Accurately identify different types of waste materials
  • Process items in real-time at high throughput
  • Integrate with robotic systems for physical sorting
  • Adapt to different waste types through training

Solution Overview

This system addresses these challenges through:

Computer Vision

YOLOv11-based segmentation model for accurate trash detection

Deep Learning

PyTorch-powered neural networks with hardware acceleration

Real-time Processing

Video stream analysis with object tracking and trajectory mapping

Robotics Integration

VEX arm controller coordination for automated physical sorting

System Capabilities

Three-Class Classification

The system classifies waste into three main categories:
  1. Cardboard and Paper - Recyclable paper products
  2. Metal - Aluminum cans, steel containers, and metal objects
  3. Plastic - Plastic bottles, containers, and packaging

Hardware Acceleration

Optimized device management supports multiple hardware configurations:
  • CUDA - NVIDIA GPU acceleration for high-performance inference
  • MPS - Apple Silicon Metal Performance Shaders for M1/M2 Macs
  • CPU - Fallback CPU processing for systems without GPU support

Visual Annotations

Rich visualization features include:
  • Mask Drawing - Color-coded segmentation masks for each waste category
  • Bounding Boxes - Detection boxes with class labels and confidence scores
  • Object Tracking - Trajectory paths showing object movement across frames

Architecture Components

The system consists of four main modules:
Handles YOLO model loading, device management, and inference. Performs real-time object detection and segmentation on video frames with confidence thresholding.
Provides visualization components for masks, bounding boxes, and tracking trajectories. Renders color-coded annotations on processed frames.
Coordinates the classification pipeline by orchestrating segmentation and drawing operations. Main entry point for frame-by-frame processing.
Manages VEX arm controller communication, sensor feedback, safety protocols, and scanning operations for physical waste sorting.
