光学字符识别 [英] OPtical Character Recognition

问题描述

我是VB.NET的新手，我需要在VB.NET中为我的项目开发光学字符识别。任何人都可以帮我一个示例代码??

I m new to VB.NET and I need to develop an optical character recognition in VB.NET for my project. Can anybody help me with a sample code??

推荐答案

这并不像你想象的那么容易。



如果很难找到，开源OCR的质量可以接受。一个流行的开源项目有.NET包装器是Tesseract：

http：// en.wikipedia.org/wiki/Tesseract_%28software%29 [ ^ ]。



这是其中一个.NET项目： http://code.google.com/p/tesseractdotnet/ [ ^ ]。



我在CodeProject上发现了一些更有趣的作品，但我不能说它们中的任何一个都是完成;有更多的研究项目。请参阅CodeProject文章：



神经网络OCR [ ^ ]，

使用神经网络创建光学字符识别（OCR）应用程序 [ ^ ]，

神经网络分类器 [ ^ ]，

使用链码的光学字符识别（OCR）中的AC＃项目 [ ^ ]，

Unicode光学字符识别 [ ^ ]，

Hebb神经网络 [ ^ ]，

C ++中的反向传播人工神经网络 [ ^ ]，

OCR线路检测 [ ^ ]。



我必须警告你：其中一些作品是与我抱怨的质量相比，非常好，更好以上，但这些工作都没有完成到即用型应用程序中。他们都需要大量的工作才能达到这样的水平。



也许还有一些我不熟悉的新项目;因此，如果您在CodeProject和其他地方进行自己的搜索，则不会受到影响。如果您发现有什么好的话，请回复此答复的评论。

This is not as easy as you may think.

Open-source OCR of acceptable quality if quite hard to find. One popular open-source project which has .NET wrappers is Tesseract:
http://en.wikipedia.org/wiki/Tesseract_%28software%29[^].

This is one of such .NET projects: http://code.google.com/p/tesseractdotnet/[^].

I found a number of much more interesting works on CodeProject, but I cannot say any of them are complete; there are more of the research projects. Please see the CodeProject articles:

Neural Network OCR[^],
Creating Optical Character Recognition (OCR) applications using Neural Networks[^],
Neural Network Classifier[^],
A C# Project in Optical Character Recognition (OCR) Using Chain Code[^],
Unicode Optical Character Recognition[^],
Hebb neural network[^],
Backpropagation Artificial Neural Network in C++[^],
OCR Line Detection[^].

I have to warn you: some of these works are very good, much better compared to the quality I complained about above, but none of these works is completed into a ready-to-use application. They all require considerable amount of work to complete to such level.

Maybe there are newer projects I''m not familiar with; so it would not hurt if you do your own search in CodeProject and elsewhere. Please, if you find something good, please reply in the comment to this answer.
