Small javascript app for quick compare two images (mainly coins images)
Main idea - if we have two images and want compare it, we need align it first via translating, scaling and rotation. In javascript we have setTransform method of canvas’ context that can do this transformation, but we need parameters for it. The simplest way to get it is note 3 equal points in each image. When we now it, we can write lineart equation system based on transfom formula.
Project has two branches:
clearVersion - is fully functionally project
master - is uses on github.io, it contains some metrics also which isn’t a part of current project actually. Maybe I will add some adverts to this branch in the future.
Disscusion on collectors’ forum coins.su (in Russian)
Also I have written an iOS version
ualgebra.js is used for solving equation system
