I built real-time glasses detection that runs entirely in the browser (ONNX + WebGPU)

I’ve been playing with browser-based computer vision for a while, and I ended up building something I didn’t expect to feel this fast in practice. It’s called FrameFind. The first module detects whether someone is wearing glasses in real time, but the interesting part isn’t the feature itself — it’s how it runs.
