Development of IOS bank card number identification _ios

IOS Open CV

There's a big idea.

1. Capture bank card image, intercept to character area

2. The most captured image for processing, denoising, binary,

3. The bank card number area for cutting division, and then contrast characters

OPENCV installation failed, direct download dragged into the Xcode words, will report the following error

Workaround:

1. Download and install Libjpeg, will

Copy to the project, then add a few framework:CoreVideo.framework, Assetslibrary.framework, Coremedia.framework.
