Field Detail

inImage

protected Image inImage

The input image. It should have a size inHeight*inWidth*inDepth

inHeight

protected int inHeight

inWidth

protected int inWidth

inDepth

protected int inDepth

bounds

protected int[] bounds

This gives the minX,maxX, minY,maxY pixel values for the current output image. We can use this to limit the region of the input image we are interested in.

outImage

protected Image outImage

The output image. It should have a size outHeight*outWidth*outDepth

outHeight

protected int outHeight

outWidth

protected int outWidth

outDepth

protected int outDepth

trans

protected Transformer trans

The transformation from the output image to the input image.

Constructor Detail

Sampler

public Sampler()

Method Detail

sample

public abstract void sample(int index)

Find the value in the input data to put in the output data. The output array defined in a previous setOutput call is updated.

Parameters:

index - The index into the output array.

clone

public java.lang.Object clone()

Allow someone to get a copy of this sampler for use on another image.

Overrides:

clone in class java.lang.Object

setInput

public void setInput(Image inImage)

Set the input image for the sampling

setBounds

public void setBounds(int[] bounds)

Set the bounds of the output image that may be asked for.

setOutput

public void setOutput(Image outImage)

Set the output image for the sampling

setTransform

public void setTransform(Transformer transform)

Set the transformation information.

Parameters:

transform - The transformer object.

factory

public static Sampler factory(java.lang.String type)

Factory for creating samplers

setOrder

public void setOrder(int order)

Set the order of the classifier. By default this does nothing but it defines the order of the sampling for some samplers.
