First, I sent this once but I don't think it made it onto the list. I've done a quick search of the archives and couldn't find it. I apologize in advance if this end up being a double post.
Hi everyone, I'm trying to write a bilateral filter using Core Image with the specific goal of having it preform the filter on the GPU for high performance as this will be for large 4d data sets. I started out by reading the Core Image Programming Guide and came to the "Writing Nonexecutable Filters" page and came across this sentence: "Core Image assumes that the ROI coincides with the domain of definition. This means that nonexecutable filters are not suited for such effects as blur or distortion." Does this mean that it is not possible to write a bilateral filter which does the computations on the GPU? I've looked at the Core Image gaussian filter. Thus far I cannot find out whether it is executed on the CPU or GPU and I was wondering if there is a way to determine this. Is there source code available for this filter and if so where is it? I have had no luck finding it so far. Also, if anyone has experience with this type of filter and could point me in the right direction for implementing it with Core Image it would be much appreciated. Lots of questions I know, but I hope someone can help.
