Ooh, nice!

I found this interesting repo [1] + document [2] on image processing
algorithms. I'll post it on the libcamera Open Projects page too.

[2] https://github.com/cruxopen/openISP/blob/master/docs/Image%20Signal%20Processor.pdf

I'll update the Open Project page on this soon, but besides OpenCL,
OpenGL compute shaders might also be another option for implementation
on a GPU, so looking into those would be useful too. Drafting an
implementation on CPU is good too though, of course.
