Class SparseGradientSafe<T extends ImageGray,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 ImageGray,G extends GradientValue>
extends java.lang.Object
implements SparseImageGradient<T,G>

Wraps around other SparseImageGradient classes and checks to see if the image is in bounds or not. If it is out of bounds the return value 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 ImageGray>

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 ImageGray>

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 ImageGray,G extends GradientValue>

Parameters:

x - x-axis pixel coordinate

y - y-axis pixel coordinate

Returns:

Gradient at that point.

getGradientType

public java.lang.Class<G> getGradientType()

Specified by:

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