Class SparseGradientSafe<T extends ImageSingleBand,G extends GradientValue>

java.lang.Object

boofcv.struct.sparse.SparseGradientSafe<T,G>

All Implemented Interfaces:

SparseImageGradient<T,G>, SparseImageOperator<T>

public class SparseGradientSafe<T extends ImageSingleBand,G extends GradientValue>
extends Object
implements SparseImageGradient<T,G>

Wraps around other SparseImageGradient classes and checks to see if the image is in bounds or not. If not the gradient is set to one.

Method Detail

setImage

public void setImage(T input)

Description copied from interface: SparseImageOperator

Specifies the image being processed.

Specified by:

setImage in interface SparseImageOperator<T extends ImageSingleBand>

Parameters:

input - Image being processed

isInBounds

public boolean isInBounds(int x,
                 int y)

Description copied from interface: SparseImageOperator

Checks to see if the entire sample region is contained inside the image or not. Depending on the implementation it might be able to handle out of bounds pixels or not.

Specified by:

isInBounds in interface SparseImageOperator<T extends ImageSingleBand>

compute

public G compute(int x,
        int y)

Description copied from interface: SparseImageGradient

Computes the gradient at the specified point.

Specified by:

compute in interface SparseImageGradient<T extends ImageSingleBand,G extends GradientValue>

Parameters:

x - x-axis pixel coordinate

y - y-axis pixel coordinate

Returns:

Gradient at that point.

getGradientType

public Class<G> getGradientType()

Specified by:

getGradientType in interface SparseImageGradient<T extends ImageSingleBand,G extends GradientValue>
