Package com.aparapi.examples.median

Class MedianKernel7x7

java.lang.Object
com.aparapi.Kernel
com.aparapi.examples.median.MedianKernel7x7
All Implemented Interfaces:
Cloneable
public class MedianKernel7x7
extends com.aparapi.Kernel
Provides support for pixel windows of size no greater than 49 (e.g. 7x7).

Demonstrates use of __private array for (partial) sorting, also demonstrates @NoCl annotation for specialised use of ThreadLocal in JTP execution.
