Builds an AR marker detector in plain JavaScript using canvas and video input, reads getImageData RGBA array, converts to luma grayscale + threshold to pull bright regions, runs blob labeling and edge tracing to find connected components and corners, computes a homography to warp the distorted patch and does a pixel‑by‑pixel match against a reference (requires ~100px marker). Uses Web Workers to keep UI responsive; demo works in the browser though code is simple and not performance‑optimized.
