public class Kernel extends Object implements 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 filter matrix element
that corresponds to the pixel position for which an output value is
being computed.| Constructor and Description |
