Struct WindowSpan 

pub struct WindowSpan {
    pub behind: usize,
    pub ahead: usize,
}

How many source frames a windowed operation needs behind and ahead of its target frame, target frame itself not counted in either number.

reseed needs exactly behind + 1 + ahead frames, oldest first, with the target frame sitting at index behind. This is what tells a caller like reseed how wide a window to build, and it varies by algorithm because nl4d’s own cross-frame accumulator needs more forward context than the NLM algorithms do. See Denoiser::window_span.

Fields

behind: usize

How many frames older than the target the window must include.

ahead: usize

How many frames newer than the target the window must include.
