I want to develop an iPhone application that is going to convert some sort of images to text formats. I want to know that is there any built-in library for achieving this purpose?

推荐答案

我想您是在问有关从图像(OCR)识别文本的问题，而不是关于将图像文件编码为base64的问题

I suppose you are asking about recognizing text from images (OCR) and not about something like encoding image file into base64

iPhone中没有内置的OCR库.

There's no build-in OCR libraries in iPhone.

根据您的预算以及要达到的精度，您可以尝试

Depending on your budget and what accuracy you trying to achieve, you can try

• 商用OCR-来自ABBYY http://abbyy.com/mobileocr/iphone 的MSDK -高精度，客户支持等，但要花钱.免责声明:我为ABBYY工作
• 开放源代码OCR-Tesseract http://code.google.com/p/tesseract- ocr/-完全免费，但准确性较低.此示例显示了如何在iPhone上运行它: https://github.com/nolanbrown/Tesseract-iPhone -演示

• Commertical OCR - MSDK from ABBYY http://abbyy.com/mobileocr/iphone - high accuracy, customer support, etc. but costs money. Disclaimer: I work for ABBYY
• Open Source OCR - Tesseract http://code.google.com/p/tesseract-ocr/ - completely free, but less accurate. This sample shows how to run it on iPhone: https://github.com/nolanbrown/Tesseract-iPhone-Demo
