Package boofcv.alg.weights

Class WeightPixelKernel_F32

java.lang.Object

boofcv.alg.weights.WeightPixelKernel_F32

All Implemented Interfaces:

WeightPixel_F32

Direct Known Subclasses:

WeightPixelGaussian_F32

public abstract class WeightPixelKernel_F32
extends Object
implements WeightPixel_F32

Weight which uses the values contained in a Kernel2D_F32. For performance reasons no checks are done to see if a request has been made outside the kernel's radius. Those values should be zero.

Method Details

weightIndex

public float weightIndex(int index)

Description copied from interface: WeightPixel_F32

Faster way to access the weight. Refers to the index in a row major matrix.

x = (index % widthX) - radiusX
y = (index / widthX) - radiusY

Specified by:

weightIndex in interface WeightPixel_F32

Parameters:

index - index of grid element

Returns:

the weight

weight

public float weight(int x,
 int y)

Description copied from interface: WeightPixel_F32

Access the weight using coordinates.

Specified by:

weight in interface WeightPixel_F32

Parameters:

x - x-coordinate: range = -radius to radius, inclusive

y - y-coordinate: range = -radius to radius, inclusive

Returns:

the weight

getRadiusX

public int getRadiusX()

Description copied from interface: WeightPixel_F32

Returns the kernel's radius along the x-axis

Specified by:

getRadiusX in interface WeightPixel_F32

Returns:

Radius of kernel

getRadiusY

public int getRadiusY()

Description copied from interface: WeightPixel_F32

Returns the kernel's radius along the y-axis

Specified by:

getRadiusY in interface WeightPixel_F32

Returns:

Radius of kernel
