The Challenge

• False positive shrink alerts exceeded 30%
• Store variability (lighting, camera angles, SKU churn)
• Seasonal patterns missing in training data
• Cross-modal mismatch between vision & POS data
• No dataset versioning or governance layer

Customer Overview

A US-based retail chain deployed AI combining computer vision, POS logs, and inventory data for shrink detection, shelf monitoring, and loss prevention analytics — but performance degraded at scale.

DXW Approach

• Dedicated domain-trained annotation team embedded with client systems
• Re-engineered dataset lifecycle across vision, structured data, and MLOps
• Re-annotated 1.2M+ image & video frames using CVAT & Roboflow
• Built unified SKU + POS taxonomy for cross-modal alignment
• Integrated pipelines with MLflow, CI/CD, feature stores & drift monitoring

Computer Vision Refinement

Bounding box precision, segmentation, keypoint labeling, and occlusion taxonomy improvements.

Cross-Modal Alignment

Unified SKU + POS taxonomy eliminated misclassification between visual and transactional data.

Video Optimization

Improved multi-object tracking, motion continuity, and event-based interaction labeling.

MLOps Integration

Dataset versioning, metadata tracking, CI/CD integration, and controlled retraining workflows.
