# Basic Meanshift routines

meanShift :: Double -> [Vector] -> Vector -> VectorSource

Calculate the Mean shift for a point in a dataset. This is efficient only when we cannot make an a priori estimate on which points contribute to the mean shift at given location.

meanShiftWindow :: Int -> Window -> Double -> Vector -> VectorSource

Mean shift with a windowing function. Performing mean shift is more efficient if we can index and calculate only those points that are in the support of our kernel.

# Auxiliary functions for iterating the meanshift steps.

fixedPoint :: Eq a => (a -> a) -> a -> [a]Source

Find a path to the fixed point of a function.

fixedPointE :: Double -> (Vector -> Vector) -> Vector -> [Vector]Source
