C# Class Emgu.CV.Cvb.CvBlobDetector

Wrapper for the CvBlob detection functions. The Ptr property points to the label image of the cvb::cvLabel function.

Algorithm based on paper "A linear-time component-labeling algorithm using contour tracing technique" of Fu Chang, Chun-Jen Chen and Chi-Jen Lu.

Inheritance: Emgu.Util.UnmanagedObject
