Geometrical moments are attractive for image-distortion invariant pattern recognition. Orientation scale and position of the image are readily determined by its moments. Rotation-, scale- and shift-invariant features can also be extracted using moment invariants. Some optical methods for generating image moments have been proposed and a single-chip VLSI implementation for generating real-time 2-dimensional image moments has recently been achieved. The applications of the moment method will be further expanded.
