Class CannyEdgeDetector2

java.lang.Object

org.openimaj.image.processing.edges.CannyEdgeDetector2

All Implemented Interfaces:

ImageProcessor<FImage>, Processor<FImage>, SinglebandImageProcessor<Float,FImage>

Deprecated.

@Deprecated
public class CannyEdgeDetector2
extends Object
implements SinglebandImageProcessor<Float,FImage>

This implementation is deprecated and is only kept for backward-compatibility of old EdgeDirectionCoherenceVector features. Use the CannyEdgeDetector instead.

This is an implementation of the canny edge detector that was found somewhere out there on the web with no attribution. If this is your code and you don't want it in OpenIMAJ, please let us know.

Default constructor

Method Detail

isImageReady

public boolean isImageReady()

Deprecated.

Returns:

Returns whether the processing has completed.

processImage

public void processImage(FImage image)

Deprecated.

Process an image. Implementing classes must alter the image passed in-place or assign the output to the input using Image.internalAssign(Image).

Specified by:

processImage in interface ImageProcessor<FImage>

Parameters:

image - The image to process in place.
