Function visual_odometry_rs::core::inverse_depth::fuse

pub fn fuse<F>(
    a: InverseDepth, 
    b: InverseDepth, 
    c: InverseDepth, 
    d: InverseDepth, 
    strategy: F
) -> InverseDepth where
    F: Fn(&[(Float, Float)]) -> InverseDepth, 

Fuse 4 inverse depth pixels of a bloc with a given merging strategy.

It only keeps the known values and passes them as a Vec into the given strategy.
