Image Moment - Scale Invariant Moments

Scale Invariant Moments

Moments η_{i j} where i + j ≥ 2 can be constructed to be invariant to both translation and changes in scale by dividing the corresponding central moment by the properly scaled (00)th moment, using the following formula.

$\eta_{ij} = \frac{\mu_{ij}} {\mu_{00}^{\left(1 + \frac{i+j}{2}\right)}}\,\!$

Famous quotes containing the words scale and/or moments:

“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (1894–1963)

“All the strong agonized men
Wear the hard clothes of war,
Try to remember what they are fighting for.
But in dark weeping helpless moments of peace
Women and poets believe and resist forever.”
—Muriel Rukeyser (1913–1980)
