The Challenge:
Retailers want to know not just how many people visit their stores, but who they are—age group, gender, shopper type. Yet demographic AI is notoriously tricky: global models often fail to capture local nuances. For example, a model trained on European datasets might misclassify age ranges or shopper profiles when applied in India or the Middle East.
Our Approach: Global + Local Models
At FootfallCam, we start with a global demographic model, trained on millions of annotated samples from diverse geographies. This provides a strong baseline and ensures the model can recognise universal human features across multiple environments.
But the real leap in accuracy comes from the local adaptation layer:
- Each deployment can “learn” from its own environment.
- The model fine-tunes on region-specific facial features, attire, cultural demographics, and shopper behaviours.
- Over time, accuracy increases as the system adapts to local reality instead of applying a one-size-fits-all approach.
Annotation App: Taking Accuracy to the Next Level
To bridge the gap, we introduced an Annotation App. This tool allows operators and retailers to contribute ground-truth data:
- Tagging misclassified demographics (e.g., correcting an age group).
- Feeding back verified samples into the training loop.
- Enabling collaborative crowdsourced improvement across regions.
With this process, the demographic AI doesn’t stay static—it evolves. Each correction sharpens the accuracy not only for that specific store but also for the global model, benefiting all users worldwide.
The Result:
- Higher precision in age and gender classification across different regions.
- Cultural adaptability, ensuring the model understands local shopper demographics.
- Continuous improvement, powered by retailer feedback and our annotation ecosystem.
Why It Matters:
For retailers, this means they can confidently rely on demographic insights for critical decisions: from store planning and marketing campaigns to staffing and customer experience strategies. Accurate data translates directly into better business outcomes.
