Image processing in the gradient domain https://en.wikipedia.org/wiki/Gradient-domain_image_processing is quite a powerful tool. It requires however a Poisson solver, which I can not find in the IPP libraries. There is a Poisson solver in the MKL library.
For image processing in the gradient domain, do you recommend to use the Poisson solver in the MKL library ? Or a hand-crafted solver using Fast Fourier Transforms ? Or anything else ?
