typed op• Data kinds: cimage → cimage
• Call: fullseye.apply(img, "tb_cx_apply_transfer_function", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
*No figure: this op takes cimage as input. A Studio program starting from an image cannot reach that type — see the runnable examples below for how it is used.*
Multiply a centred spectrum by a filter `H -> (H, W)` complex128.
The honest primitive under `ops.lowpass / ops.highpass`, but
complex-preserving: the filtered spectrum is returned as a complex field
(not immediately inverted and real-cast), so it can be chained, inspected, or
handed to :func:cx_ifft. `H` is a same-shape transfer function laid out in
the *centred* convention of :func:cx_fft (DC at the centre); it may be real
(a magnitude mask) or complex (a phase-shifting filter). A real `cx` is
FFT'd first (module convenience).
Typed bridge of the 2d op `cx_apply_transfer_function into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.

• Operator provenance and references — the sources of the research/methods this op family came from.
