Properties

ApertureSize

Gets or sets the aperture parameter for the Sobel operator.

[Range(3, 7)]
[Precision(0, 2)]
[TypeConverter(typeof(OddKernelSizeConverter))]
public int ApertureSize { get; set; }

Property Value

int

Threshold1

Gets or sets the first threshold. The smallest threshold is used for edge linking and the largest to find initial edge segments.

[Range(0, 2147483647)]
public double Threshold1 { get; set; }

Property Value

double

Threshold2

Gets or sets the second threshold. The smallest threshold is used for edge linking and the largest to find initial edge segments.

[Range(0, 2147483647)]
public double Threshold2 { get; set; }

Property Value

double

Methods

Process(IObservable<IplImage>)

Applies the Canny algorithm for edge detection to each image in an observable sequence.

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

Parameters

source IObservable<IplImage>

The sequence of images from which to extract edges.

Returns

IObservable<IplImage>

A sequence of IplImage objects where each non-zero pixel represents an image element which has been classified as an edge.
