Methods

Process(IObservable<IplImage>)

Finds the contours of connected components for each binary image in an observable sequence.

public override IObservable<Contours> Process(IObservable<IplImage> source)

Parameters

source IObservable<IplImage>

The sequence of binary images for which to find the connected component contours.

Returns

IObservable<Contours>

A sequence of Contours objects representing the hierarchy of polygonal contours extracted from each binary image.
