c＃中的blob检测 [英] blob detection in c#

问题描述

我是c＃和图像处理的新手。我想建立一个程序，将A4尺寸的纸张作为输入，检测或计算纸张上的黑色斑点。

Plz帮助我

i am new to c# and image processing. I want to build a program which take an A4 size sheet as an input and detects or count the black blobs present on the paper.

推荐答案

我在AForge.NET中使用blob识别;它对我来说效果很好，表现出惊人的性能和准确性。请参阅：

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

对于blob识别，下载后会有一个演示应用程序所有的源代码。添加功能很容易。通常，您需要在识别之前对图像执行一些其他转换。首先，我建议将对比度增加到最大值。在某些情况下，如果您需要的功能应该通过微妙的不同颜色识别，则需要执行颜色转换。依此类推......

I used blob recognition with AForge.NET; it worked very well for me, demonstrated amazing performance and accuracy. Please see:

For blob recognition, there is a demo application which you will find after you download all the source code. Adding features to it was easy. Typically, you would need to perform some other transformations to the image before recognition. First of all, I would recommend to increase contrast to maximum. In some cases, you need to perform color transformations, if the features you need should be recognized by subtly different color. And so on…

你可以使用EmguCV [ ^ ]，图像处理库OpenCV的.NET包装器。



要检测EmguCV中的blob，请使用看这里：

You can use EmguCV[^], the .NET wrapper of the image processing library OpenCV.
