推荐答案
with Tesseract ...
a简单google的training tesseract显示此页面：
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract
其中必须选择要培训的tesseract版本。
虽然3是最新版本，它是全新的，因此人们仍然淘汰任何问题 - 仍然使用版本2.4。无论如何，你会看到有大约9个步骤在训练tesseract一个特定的语言（或应该被称为字体或字符集）。你也可以使用现有的eng语言 - 但这取决于你的应用程序。例如，在我的应用程序中，我必须做文档分析，并采取一个特定的区域，并希望OCR一个13个字符的数字字符串 - 我需要高精度 - 我不想要读取'5'作为' S'和'0'作为'O'等，所以它是逻辑上创建一个特定的语言的我的特定字体集只包含字符0..9，而你可能不在乎，如果你得到额外的
I have some experience with Tesseract... a simple google of 'training tesseract' reveals this page: http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract where you must choose which version of tesseract you wish to train.. While 3 is the latest version, it's brand new and thus people are still ironing out any issues - im still using version 2.4. Anyways, you'll see there are about 9 steps in training tesseract for a particular 'language' (or what should have been called 'fonts' or 'character-sets'). You could also just use the existing 'eng' language - but it depends on your application. For example, in my application I would have to do the document analysis and take a particular region and want to OCR a 13-character string of numbers - and I needed high accuracy - and I didn't want it reading '5' as 'S' and '0' as 'O' etc, so it was logical to create a particular 'language' of my particular font-set consisting only of the characters 0..9, whereas you might not care if you get extra 'noise
