Multiple multisize image convolution


I need to implement efficiently multiple multisize image convolution. I mean that I need convolve one image (640x480) with multiple small matrix (8x8, 7x7, 5x5).

Before doing such exercise myself I’ve search for ready implementation.
I’ve found some examples of convolution in SDK samples, but they are limited to some cases.

Does somebody know ready to use implementation of Multiple multisize image convolution ?

Thank you

I have finished an image filter with 5*5 gauss template.i think the major problem matters which memory mode to choose.i choosed texture mode
