All Implemented Interfaces:

IProgressEmitter, ICancelable, IProcessingTask, Runnable

public class TemplateMatchingWithRasters
extends ImageProcessingTask

This class demonstrates an implementation of a basic Template Matching algorithm, using Raster(s) to access the data. This class inherits from ImageProcessingTask. IMPORTANT: This implementation does not lock access to the data while the template matching is being done.

Constructor Detail

TemplateMatchingWithRasters

public TemplateMatchingWithRasters(javax.media.jai.PlanarImage input,
                                   javax.media.jai.PlanarImage template)

The constructor for this class, which gets the input images and set some parameters.

Parameters:

input - the input image.

template - the template matching mask.

Method Detail

getSize

public long getSize()

This method returns a measure of length for the algorithm. We will consider the number of processed lines.

Specified by:

getSize in class ImageProcessingTask

Returns:

the size of the image processing size.

getPosition

public long getPosition()

This method returns a measure of the progress of the algorithm.

Specified by:

getPosition in class ImageProcessingTask

Returns:

the position of the task processing.

run

public void run()

This method is the main driver of the algorithm, it will perform the template matching.

Specified by:

run in interface Runnable

Specified by:

run in class ImageProcessingTask

isFinished

public boolean isFinished()

This method tells whether the algorithm has finished.

Specified by:

isFinished in class ImageProcessingTask

Returns:

true if the processing task has finished.

getOutput

public javax.media.jai.TiledImage getOutput()

This method returns the output image.

Returns:

the template matching resulting image.
