I am developing a OCR app for scan IC card and passport.

Now I want to crop the IC card by detecting the edges.

For an example:

I have tried https://github.com/mmackh/IPDFCameraViewController but its not very accurate for white card on a white background.

I am searching for something like the "Border Detector" uses BlinkID ios library https://github.com/BlinkID/blinkid-ios

Can anyone suggest me a good library for live detecting borders of a image and crop.

  • Checkout [OPENCV](http://docs.opencv.org/2.4/doc/tutorials/ios/image_manipulation/image_manipulation.html) for image processing, it has many such features you require. – iphonic May 15 '17 at 04:49

Instead, describe the problem and what has been done so far to solve it. – Piglet May 15 '17 at 09:43
