# Visionary — fine-grained vehicle recognition (runs in your browser)

Upload a car photo → **YOLOv8n** localises the vehicle → an adaptive **CLAHE**
illumination gate (OpenCV.js) normalises dark or flat images → an INT8
**ConvNeXt** fine-tuned on Stanford Cars identifies **make, model and year**
(196 classes) with temperature-calibrated confidence. Intermediate classical-CV
stages (CLAHE, bilateral filter, Canny, contours) are shown for every image.

Everything runs locally via ONNX Runtime Web + OpenCV.js; photos never leave the device.

Official test set (8,041 unseen images): **94.1% Top-1 / 99.1% Top-5** (Lite, default) · **94.4 % with Pro** (ConvNeXt-Small @320).
