I have an image processing kernel that performs a discrete wavelet transform on a 2D image.
When I run the kernel on my laptop with mobile HD 5000 series GPU, the result looks correct.
When I run the same kernel on my desktop with HD 7700 series GPU, there are image artifacts
at the boundaries of certain wavelet sub bands.
Same kernel, different result.
I would like to get to the bottom of this; can anyone suggest a good way of trouble shooting this kind of issue?
