Every shift is defined by a mean shift vector. The mean shift vector always points toward the direction of the maximum increase in the density. At every iteration the kernel is shifted to the centroid or the mean ...

Its extremum will be at a fine scale. At a coarse scale, this small blob will be washed out. For a large blob, computing the score at a fine scale does not produce an extremum. greenways realty covington va
