Volkus Scan — On-Device Demographic Demo

A project by Qalarc — AI systems studio, Sydney, Australia. Built, shipped and maintained by Qalarc.

The volkus.net model stack running in your browser: MediaPipe FaceMesh + four ONNX models estimate age, gender, ethnicity and skin tone live from your webcam. No frame ever leaves the device.

A transparent demo of the face-analysis pipeline that powers volkus.net. Click start, and MediaPipe FaceMesh finds your face; 224×224 crops feed four ONNX models (race, gender, age regression, and a fused age model conditioned on the demographic one-hot) through onnxruntime-web's WASM backend, rolling-averaged over a 10-second scan. You see everything the models see: the live probability distributions, the age estimate, the skin-tone classification from forehead sampling — and the honest error bars. The page makes zero network calls after model load; the ~35MB of models are served same-origin and cached.

• Full 7-class probability distributions shown honestly

• Skin-tone (Fitzpatrick/ITA) classification from forehead sampling
