Sliding tiles as in mapwindows?

[mkitti]

Would it make sense to implement a sliding tile strategy here similar to mapwindows in ImageFiltering.jl?

It makes sense to also provide some higher-order functions, not just mapwindows. We do plan to move the core image-unrelated functionalities from ImageFiltering to some not-yet-existing package in JuliaArrays. According to the JuliaHub results, all the direct dependencies of this package are JuliaImages packages, so start a new module here to host the codes sounds okay to me.

The difficulty might be due to the fact that it's quite hard to get the optimal implementation if calling these higher-order functions, see also: JuliaImages/ImageFiltering.jl#225

@mkitti interesting thought, but I think this is a bit sideways of the original purpose.
The main point was to allow an easy way to have procedures run only on a single tile and stritch the results together in the end. Not sure, if this approach is really up to provide general real-space convolution with stencils.
For that application, I am hoping for Tullio getting a better match to Cuda.
