Function imageproc::filter::vertical_filter

pub fn vertical_filter<P, K>(image: &Image<P>, kernel: &[K]) -> Image<P> where
    P: Pixel + 'static,
    <P as Pixel>::Subpixel: ValueInto<K> + Clamp<K>,
    K: Num + Copy, 

Returns horizontal correlations between an image and a 1d kernel. Pads by continuity.
