this is a two-stage perception project, first it detects a hand region in an image, then classifies how many fingers are raised. i built the whole thing from the annotation tooling through training to a flask demo you can actually interact with.
what i built
- pytorch models for hand-box detection and digit-count classification
- annotation tooling and notebooks for training and evaluation
- flask inference server and browser-facing prediction flow
how it works
- 1capture or upload an image
- 2predict a hand bounding box from the full frame
- 3crop the detected region and run digit classification
- 4return the predicted count through the flask API
what's next
- clean up dependencies for easier reproducible setup
- capture an inference demo GIF showing hand detection through digit classification
