stefanw / photoscan.js

JS app that takes photos and tries to find paper document outlines to extract a scan-like image.

photoscanjs

JS library and Vue component to take a user provided picture, detect a document and transform that part of the picture to get a scan-like image of the document.

Demo

Warning: this uses opencv.js which is 11 MB of JavaScript and uses a lot of memory. This project was tested on some mobiles, but only works in memory-limited environment when the app's internal debug mode is turned off. This might severly limit your mobile use case. jsfeat could be an alternative, but seems to be missing some features that are needed and available in OpenCV like contour detection.
