光学标记识别 [英] Optical mark recognition

问题描述

是否有任何免费的OMR库供asp.net获取扫描的.tif图像并将结果保存到sql数据库？

解决方案

首先，请参见开源AForge.NET：

http://en.wikipedia.org/wiki /AForge.net [ ^ ]，

http://www.aforgenet.com/ [ ^ ]。



或者，考虑一下Emgu CV：

http://www.emgu.com/wiki/index.php/Main_Page [ ^ ]。



这是一个OpenCV图像处理库的跨平台.Net包装器;和OpenCV是一个开源的C ++计算机视觉库：

http://en.wikipedia.org/ wiki / OpenCV [ ^ ]，

http://opencv.org/ [ ^ ]。







还有一些工作更接近ORM。更确切地说，它是OCR，但您可以将它用于OMR目的（ http://en.wikipedia.org/wiki/ Optical_mark_recognition [ ^ ]）。



请参阅：

http：// www。 atalasoft.com/products/dotimage/ocr [ ^ ]，

http://www.pixel-technology.com/freeware/tessnet2 / [ ^ ]。



不幸的是，我必须警告你：我从来没有找到任何足够好的开源OCR解决方案。我喜欢的CodeProject解决方案很少，但是，为了最好的知识，它们都是不完整的，需要大量的工作来制作一个有效的应用程序。



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 [ ^ ]，

AC #Projec t使用链码的光学字符识别（OCR） [ ^ ]，

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：其中一些与我上面抱怨的质量相比，工作非常好，更好，但这些工作都没有完成到一个现成的应用程序中。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。如果你找到好的东西，请回答这个答案的评论。



祝你好运，

is there any free OMR library for asp.net to get a a scanned .tif image and save results to a sql database?

解决方案

First of all, please see the open-source AForge.NET:
http://en.wikipedia.org/wiki/AForge.net[^],
http://www.aforgenet.com/[^].

Alternatively, consider Emgu CV:
http://www.emgu.com/wiki/index.php/Main_Page[^].

This is a is a cross platform .Net wrapper to the OpenCV image processing library; and OpenCV is an open-source C++ computer vision library:
http://en.wikipedia.org/wiki/OpenCV[^],
http://opencv.org/[^].

[EDIT]

There are also some works closer to ORM. More exactly, it''s OCR, but you can use it for OMR purposes (http://en.wikipedia.org/wiki/Optical_mark_recognition[^]).

Please see:
http://www.atalasoft.com/products/dotimage/ocr[^],
http://www.pixel-technology.com/freeware/tessnet2/[^].

Unfortunately, I must warn you: I never found any Open-Source OCR solutions which would be good enough. There are few CodeProject solutions I like, but, to best of knowledge, they are all incomplete, would need serious amount of work to make a working application out of them.

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.

Good luck,
