Constructor Detail

SparseIntegralGradientKernel

public SparseIntegralGradientKernel(IntegralKernel kernelX,
                            IntegralKernel kernelY)

Method Detail

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>

setImage

public void setImage(T integralImage)

Description copied from interface: SparseImageOperator

Specifies the image being processed.

Specified by:

setImage in interface SparseImageOperator<T extends ImageSingleBand>

Parameters:

integralImage - Image being processed

compute

public GradientValue_F64 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,GradientValue_F64>

Parameters:

x - x-axis pixel coordinate

y - y-axis pixel coordinate

Returns:

Gradient at that point.

getGradientType

public Class<GradientValue_F64> getGradientType()

Specified by:

getGradientType in interface SparseImageGradient<T extends ImageSingleBand,GradientValue_F64>
