ORB descriptor similarity — multi-image demo

Uses cv.ORB from OpenCV.js. Every pair of images is compared: for each descriptor find the Hamming distance of the 256 descriptor bits, computed in a separate wasm module built from src/popcnt.ts. Pairs with the most low-distance matches are the most similar.

descriptors per image 200 max match distance 50

Choose two or more images to compare.
