Study on Region Moment of Planner Objects Combining with the Affine Invariant Feature

The Fourier describer only describes the boundary shape of the planner target region, and cannot reflect feature inside characteristics. In this paper, the gray distribution of target region is used to describe the target characteristics and boundary shape, and get to reflect the affine invariant feature inside characteristics, which can reflect the origin characteristics more completely. The experiment shows that moment invariants can get very accurate results for the image of affine transformation.
