boofcv.struct.convolve.Kernel2D_F32

public class Kernel2D_F32
extends Kernel2D

This is a kernel in a 2D convolution. The convolution is performed by convolving this kernel across a 2D array/image. The kernel is square and has the specified width. To promote reuse of data structures the width of the kernel can be changed. All elements in this kernel are floating point numbers.

Kernel2D_F32

public Kernel2D_F32(int width,
            float... data)

Creates a new kernel whose initial values are specified by data and width. The length of its internal data will be width*width. Data must be at least as long as width*width.

Parameters:

width - The kernels width. Must be odd.

data - The value of the kernel. Not modified. Reference is not saved.

Kernel2D_F32

public Kernel2D_F32(int width)

Create a kernel whose elements are all equal to zero.

Parameters:

width - How wide the kernel is. Must be odd.

protected Kernel2D_F32()

Method Detail

wrap

public static Kernel2D_F32 wrap(float[] data,
                int width)

Creates a kernel whose elements are the specified data array and has the specified width.

Parameters:

data - The array who will be the kernel's data. Reference is saved.

width - The kernel's width.

Returns:

A new kernel.
