Where are sources for CUDA Photoshop Filters?

I found this old doc:

which used to be accompanied by GPU filter samples, but I cannot find then anywhere,
in particular I am interested in Lucy-Richardson Deconvolution in LRdeconvFilter directory.
Where is it now? I cannot believe it was just deleted
Thank you

I haven’t checked this, but the document appears to refer to CUDA samples that were part of a very early CUDA toolkit version, around 1.1 or 2.0. These are still available here. You could check to see if they are part of the samples associated with one of those early toolkits.

I have no personal experience with these, and furthermore attempting to run 15 year old software without an exact duplicate of the environment that was current back then can be quite challenging.

No, I checked few of the old SDKs and they contain samples, most of which are still in the current SDK.
LRdeconvFilter is not in any of them.

And it easy to check: all SDK samples are mentioned in release notes, so if you google, for example, for:
“smokeParticles” site:https://developer.download.nvidia.com/compute/cuda/
“boxFilter” site:https://developer.download.nvidia.com/compute/cuda/
you can see exactly when they were added.
“Photoshop” site:https://developer.download.nvidia.com/compute/cuda/
“LRDeconvFilter” site:https://developer.download.nvidia.com/compute/cuda/
“cudaFilters” site:https://developer.download.nvidia.com/compute/cuda/
bring nothing other than the doc mentioned above.
These sources just vanished.

This appears to be the download link:


I was still able to download that zip file just now.
