Methods

Process(IObservable<IplImage>)

Applies a fixed threshold to each 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>

A sequence of IplImage objects where each non-zero pixel represents a value in the original image that was accepted by the threshold criteria.
