I'm having difficulty getting to grips with the new image representations in the reworked Images.jl. I think I've got some of the basics down. But now I'm trying to visualise a spectrum, and I'm stumped.
What's the correct way to create an array/image of Float64s from an
array/image of Gray{Ufixed8} (So that fft() works), and vice versa (so I
can visualize the spectrum)?
Thanks.
