Methods

Process(IObservable<IplImage>)

Applies an adaptive threshold to every grayscale image in an observable sequence.

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

Parameters

source IObservable<IplImage>

The sequence of images to threshold.

Returns

IObservable<IplImage>

The sequence of thresholded images.
