Detailed Description

Compile-time separable filter kernel definition and named kernel bank.

KernelSpec<N> is a constexpr wrapper around std::array<float, N> with chainable compile-time transforms. All methods return a new KernelSpec leaving the original unchanged.

Named constants at the bottom of this file cover the standard operators. Custom kernels can be constructed inline at any call site:

constexpr auto k = KernelSpec<5>{ 1.F, 4.F, 6.F, 4.F, 1.F }.normalize(); filter_separable(src, tmp, dst, w, h, k, k);

KernelSpec<N> converts implicitly to std::span<const float> so it can be passed directly to any filter function without an explicit cast.
