## What is Image Superposition?

A small utility for comparing two images. It works very simply: the user loads two images into the app, selects the same points on each of them (3 is enough, with a larger number the result is averaged) and the app calculates a transformation when the selected points on the first and second pictures would coincide. You can upload images from the clipboard, from the documents of this application, from the photo album, or take a new photo on the camera. All calculations are performed on the device and you don't need internet connection for working with this app.
Initially, the program was developed for comparing the coins images, but there is no any technical limitation and it is possible to compare any pictures
