Function imageproc::filter::separable_filter_equal

pub fn separable_filter_equal<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 2d correlation of an image with the outer product of the 1d kernel filter with itself.
