public class Kernel extends Objectimplements Cloneable
Kernel class defines a matrix that describes how a specified pixel and its surrounding pixels affect the value computed for the pixel's position in the output image of a filtering operation. The X origin and Y origin indicate the kernel matrix element that corresponds to the pixel position for which an output value is being computed.

public Kernel(int width,
int height,
float[] data)
Kernel object from an array of floats. The first
width*
height elements of the
data array are copied. If the length of the
data array is less than width*height, an
IllegalArgumentException is thrown. The X origin is (width-1)/2 and the Y origin is (height-1)/2.
width - width of the kernel
height - height of the kernel
data - kernel data in row major order
IllegalArgumentException - if the length of
data is less than the product of
width and
height
