Design of high-order rotation invariants from Gaussian-Hermite moments

چکیده
In this paper we proposed a method to design and numerically calculate high-order rotation invariants from Gaussian–Hermite moments. We employed the invariant properties of the Gaussian–Hermite moments discovered earlier in [1] and we showed how to construct rotation Gaussian–Hermite invariants even in the cases when no explicit invariants from geometric moments are available. We verify by experiments the rotation invariance and show that we are capable of computing much higher order of Gaussian–Hermite invariants than of geometric invariants, which brings better discrimination power. & 2015 Elsevier B.V.

3D rotation invariants of Gaussian-Hermite moments
3D rotation invariants based on orthogonal Gaussian–Hermite moments are proposed in this paper. We present an elegant and easy theoretical derivation of them. At the same time we prove by experiments that the Gaussian–Hermite invariants have better numerical stability than the traditional invariants composed of geometric moments. © 2014 Elsevier B.V.

متن کاملScale invariants from Gaussian-Hermite moments
Invariants to image scaling composed of Gaussian–Hermite moments are introduced in this paper for the first time. To achieve the invariance, we propose to modulate the Gaussian–Hermite polynomial basis using variable parameter σ, the value of which depends on the input image. The scaling invariance property can be coupled with the rotation invariance presented earlier. This approach is applicab...
متن کامل2D and 3D Image Analysis by Gaussian Hermite Moments
This chapter introduces 2D and 3D GaussianHermite moments and rotation invari-ants constructed from them. Thanks to their numerical stability, GaussianHermite moments provide better reconstruction and recognition power than the geometric and most of other orthogonal moments while keeping the simplicity of design of the invari-ants. This is illustrated by experiments on real 2D and 3D data. 7.1 ...
متن کاملHermite Interpolants and Biorthogonal Multiwavelets with Arbitrary Order of Vanishing Moments
Biorthogonal multiwavelets are generated from refinable function vectors by using multiresolution analyses. To obtain a biorthogonal multiwavelet, we need to construct a pair of primal and dual masks, from which two refinable function vectors are obtained so that a multiresolution analysis is formed to derive a biorthogonal multiwavelet. It is well known that the order of vanishing moments of a...
