推荐答案

没有简单的方法-您将不得不使用OCR库: Google [ ^ ]可以提供帮助.

There is no simple way - you will have to use an OCR library: Google[^] can help.

也许格里夫(Griff)的答案需要澄清.
图像本身没有文字.图片中的文字应以人类可以识别的方式识别.
这是图像识别的问题.这个特定的应用领域非常具体，称为光学字符识别(OCR).尽管有这个通用名称，但现实生活中的引擎并不仅识别字符，而且还识别单词和句子，通常使用一些单词词典.看起来更复杂，但实际上更有效.

请参阅我过去的解决方案，其中包含以下参考: OCR软件 [ http://en.wikipedia.org/wiki/Optical_character_recognition [ http://en.wikipedia.org/wiki/List_of_optical_character_recognition_software [

Maybe the answer by Griff needs some clarification.

There is not text in images per se. The text in the image should be recognized the way human being can.
This is a matter if image recognition. This particular application field is very specific and called Optical Character Recognition (OCR). Despite this common name, real-life engines don''t merely recognize characters, they recognize words and sentences instead, usually using some word dictionary. It seems more complicated but in fact more effective.

Please see my past solution with a number of references: OCR Software[^].
