Detailed Description

Represents a Kernel Processing Unit on an Image Stream in GPGPU framework.

This object represents a computation that is invoked locally over the image specified as texture. Computation is invoked by specifying Output Coordinates in the render target and also by specifying the input texture coordinates. Thus a Kernel represents a function that maps an input Quad Memory Block to an output Quad memory block.

In simplest GPGPU scenario, the Kernel can be set up to do 1-1 Pixel to Texel Mapping. By Setting the Range of the Function we can apply the kernel to a subset of the range and also specify a subset of the function domain by appropriately choosing texture coordinates.
