public abstract class Filter
extends ChannelMapNode

A Filter is the base for 3D image filtering operations. Subclasses provide a 3D filter coefficient matrix (which is queried by the getCoefficient* functions). The filter is applied to the requested channel by sampling values for each coefficient in the matrix and then calculating the weigthed sum. The size of the sampling cube can be adjusted by the fields sx, sy and sy (in x/y/z and u/v directions).

Method Detail

accept

public void accept(ChannelMapNodeVisitor visitor)

Overrides:

accept in class ChannelMapNode

getCoefficient

protected abstract float getCoefficient(int gx,
                                        int gy,
                                        int gz)

Get the coefficient at position (gx/gy/gz) in the filter matrix. The functions getCoefficientMaskSize* are used to obtain the indexable range (i.e. sx, sy and sz), so 0 <= gx <= sx. Derived classes implement this function to provide filter coefficients. The Filter class will perform the filtering by applying those coefficients as weigths to the sampled values from the input channel.

Parameters:

gx -

gy -

gz -

Returns:

getFloatValue

public float getFloatValue(ChannelData data,
                           int channel)

Specified by:

getFloatValue in interface ChannelMap

Overrides:

getFloatValue in class ChannelMapNode

getSx

public float getSx()

getSy

public float getSy()

getSz

public float getSz()

setSx

public void setSx(float value)

setSy

public void setSy(float value)

setSz

public void setSz(float value)
