GPU Gaussian Blur Kernel Limit

asked 2013-10-31 15:33:45 -0600

The size of the kernel is currently limited to 32 x 32. I'm trying to do a blur with a kernel of size 151 x 151 or possibly even larger. What's the best way around this?

Why would you want to do that?

Downscale your image and apply a "standard-sized" Gaussian kernel. Reducing the image size amounts to removing the highest frequencies in the image which in turn is equivalent to using a large Gaussian kernel.
