Gabor Functions
Gabor functions can be rotated in 2D, and their spectral bandwidth is selectable.
Gabor functions have been widely used as filters and as transform basis functions.
These functions optimize one particular measure of locality:
where (

and (
)

are normalized second moments of the energy density.
x)2
and (
)2
are normalized second moments of the energy density.
x)2
and ()2
are normalized second moments of the energy density.
