opencv和tesseract-ocr的区别与联系

[Uncertain_Magic]

最近发现了有道词典上面的取词功能很好奇他是怎么做成的。
上网查找了有关于图像识别的资料发现介绍OCR和opencv的有很多，可是还是不是很懂两者之间到底有什么区别。
查找过ocr软件但是网上说的赛酷OCR 和汉王的文本王并没有说明什么原理，opencv里面是利用c++写算法来的，但是真正的道理本人还是不了解，CSDN上面大神比较多，还望各位大神求解！！！

opencv专注机器视觉 tesseract专注字符识别 opencv貌似研究的更广

opencv是一个计算机视觉库 open source computer vision library 可以去http://wiki.opencv.org.cn/index.php/%E9%A6%96%E9%A1%B5看看文档 tesseract-ocr https://code.google.com/p/tesseract-ocr/ Tesseract is probably the most accurate open source OCR engine available. Combined with the Leptonica Image Processing Library it can read a wide variety of image formats and convert them to text in over 60 languages. It was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but since then it has been improved extensively by Google.
