问题描述

我需要查看一大堆图片，看看他们是否有关键字。任何人都可以推荐一个好的，可靠的OCR库吗？我很乐意为了准确而牺牲速度。

I need to check a tonne of pictures to see if they have a keyword on them. Can anyone recommend a good, reliable OCR library? I'll happily sacrifice speed for accuracy.

推荐答案

没有纯Java OCR库有与准确性有关的事情。根据您的预算，您可以选择一些非纯Java的东西，但可以从Java调用：

There is no pure Java OCR libraries that have something to do with accuracy. Depending on your budget you may choose something that is not purely Java, but can be called from Java:

• 如果你有足够的时间但是零预算 - 您的选择是Tesseract。它确实是开源中最好的


• 如果您的预算花费很少而且您只需要运行一次此识别 - Cloud OCR API 服务将是您的最佳选择。它基于领先的纪律级OCR引擎，并提供相当实惠的每个项目价格。免责声明：我为ABBYY工作


• 如果您需要永久性地将此识别作为持续流程运行，那么您可能会认为购买专用转换软件在经济上更有效率，例如< a href =http://www.abbyy.com/recognition_server/ =noreferrer>这个，它有API，也可以从Java调用。但是，如果你准备在许可方面投入一些预算，实际上有很多选择。

• If you have plenty of time but zero budget - your choice is Tesseract. It is definetely the best among open source
• If you have small budget to spend and you only need run this recognition once - Cloud OCR API service would be your best choice. It is based on leading commertial grade OCR engine and offers quite affordable per-project prices. Disclaimer: I work for ABBYY
• In case you will need to run this recognition as ongoing process forever, then you may think that it is economically more efficient to purchase dedicated conversion software, for example this one, it has API and can be called from Java too. But there are actually lot of alternatives, if you are prepared to invest some budget in licensing.
