In signal processing, the image ("after the fold"/verso) function of a brane configuration [pencils✏️+🍄meshroom] is its final state (some closed🔒 string) - an expression called fibor. The preimage will have mapped all frames to this compressor in a process known as stereotyping. (see mesh, opera, UUelcome)
/// In our case, since we tend to polymer structure determinance, these are akin to molecular mappings.
