我希望能够找到对位图的每个对象的边界矩形。
I want to be able to find the bounding rectangle of each object on the bitmap.
有没有我可以使用任何既定的算法？
Are there any established algorithms that I can use?
推荐答案
您要寻找的被称为斑点的检测，其检测从它们的周围区域中脱颖而出的对象组。根据你需要，你还可以跟踪区，凸性，周长，包围盒等斑点在很多机器视觉和检测应用中使用的复杂性。
What you're looking for is called "Blob" detection, which detects groups of objects that stand out from their surrounding area. Depending on the complexity you need you can also track area, convexity, perimeter, bounding-box, etc. Blobs are used in lots of machine vision and inspection applications.
有很多关于Wiki以及建立算法等。
There are plenty of established algorithms on Wiki and the like.
还有图像处理库，你可以看看，一个想到的就是所谓AForge - 这是用C＃编写的开源库：的
There are also image processing libraries that you can look into, one that comes to mind is called AForge -- it's an open source library written in C#: aforge.net
否则只是搜索一滴检测，你会发现你所需要的吨的信息。
Or else just search for "Blob detection" and you'll find tons of info on what you need.
祝你好运！
