字符识别 [英] Character recognition

问题描述

我是matlab的新手，我正在尝试学习OCR。现在我只是试着让系统工作，然后再深入研究构建我自己的系统的理论。

I am new to matlab and I am trying learn OCR in it. For now I am just trying to get a system working before diving into the theory for constructing my own system.

无论如何我正在跟踪此处

然而，每当我尝试代码时，不仅我的矩形看起来是倒置的，而且它们也不会强加在原始图像上。

However whenever I try the code not only my rectangles appear inverted but they also aren't imposed on my original image.

我在想这个问题可能就在这里

I am thinking that the problem might be here

[Ilabel num] = bwlabel(Ifill);
disp(num);
Iprops = regionprops(Ilabel);
Ibox = [Iprops.BoundingBox];
Ibox = reshape(Ibox,[4 50]);
imshow(I)

我正在使用Matlab R2012b。在这方面的任何帮助将非常感激。

I am using Matlab R2012b. Any help in this regard would be really appreciated.

推荐答案

一些参考检查：

• 关于字符识别的mathworks文档


• Google搜索matlab字符识别


• Google搜索matlab字符识别

• the mathworks docs on character recognition
• Google results on "matlab character recognition"
• Google results on "matlab character recognition"

这些应足以帮助您顺利完成。我有类似的任务，并使用这些。 （我必须使用不同的算法识别图像中的硬币。）所以：检查所有可用的示例，检查所有/主要的现有算法示例/想法（可能在其他语言中：google.lv结果对我来说很棒！），然后将它们结合起来以更好地创建一个有效的例子。

These should be enough to help you successfully finish. I had a similar task and used these. (I had to recognise coins in image with matlab using different algorithms.) So: check all available examples, check all/main existing algorithm examples/ideas (in other languages possibly: the google.lv results were great for me!), then combine them all to better create a working example.

如果你遇到困难的另一个好资源：发表你的问题这里，在mathworks matlab中央新闻组。但是请注意：你必须在发布之前完成你的功课，因为那里的人可以提供帮助，但是（就像这里）他们不会为你解决问题。

Another good resource if you get stuck: post your question here, on the mathworks matlab central newsgroup. But be advised: you must have done "your homework" before posting, because people there can help, but (like here) they will not solve the problem for you.

祝你好运。
