iOS開發之銀行卡號識別_IOS

iOS open cv

大體有個思路

1. 捕捉銀行卡映像，截取到字元地區

2. 最捕捉到的映像進行處理，去噪比，二值化，

3. 將銀行卡號碼地區進行切割劃分，然後對比字元

opencv 安裝失敗，直接下載拖進 xcode 的話，會報以下錯誤

這裡是 詳細解決連結地址

解決方案：

1.下載安裝 libjpeg ,將

/opt/libjpeg-turbo/lib/libjpeg.a 

拷貝到項目中，然後添加幾個 framework : CoreVideo.framework, AssetsLibrary.framework, CoreMedia.framework 。
