Emgu CV Blob Detection

问题

I'm using Emgu CV 2.1 and want to have a simple blob detection. I search for white blobs in a black image. Unfortunalty I can not find out how to do this! Do I need an additional library? Or how is this function called in emgu cv? Or is there really no blob detection in emgu cv?

Thanks for any help Benks

For starters the basic Hough blob tracking method EMGU forums have an example here : (2nd Comment)

Here is the declaration sytax

You have SimpleBlobDetector class just for that , Just call Detect() on your image.

Another way is to use cannyEdgeDetection() followed with FindContours method, both in Image class .
