ATM Anomaly Detection

AI-driven anomaly detection for ATM infrastructure monitoring.

Overview

This system detects anomalies in ATM images using computer vision and machine learning:

• Physical damage (vandalism, scratches, broken screens)
• Environmental issues (graffiti, dirt, obstructions)
• Functional problems (out of service, paper jams, empty cash)
• Security concerns (skimming devices, suspicious attachments)

Quick Start

1. Place ATM images in data/raw/
2. Run preprocessing: python src/data/preprocess.py
3. Train model: python src/training/train.py
4. Run inference: python src/inference/predict.py --image <path>

Data Schema

Images

• Format: JPG/PNG
• Resolution: 1920x1080 or higher
• Naming: {atm_id}_{timestamp}_{camera_angle}.jpg

Annotations

• Format: COCO JSON or YOLO txt
• Categories: damage, graffiti, obstruction, skimming, out_of_service

Model

• Base: YOLOv8 or EfficientDet
• Input: 640x640 RGB
• Output: Bounding boxes + anomaly class + confidence

Pipeline

1. Data Collection → ATM images from field cameras
2. Preprocessing → Resize, normalize, augment
3. Training → Supervised learning on annotated data
4. Inference → Real-time anomaly detection
5. Alerting → Notify when anomalies detected
