Chinese Chess Character Recognition with Radial Harmonic Fourier Moments
—Radial harmonic Fourier moments (RHFMs) are invariant to translation, rotation, scaling and intensity, which own excellent image description ability, noise-resistant power, and ...

Rotation and cropping resilient data hiding with zernike moments
Most digital data hiding schemes are sensitive to simple geometric attacks namely rotation, cropping, and scaling. Of these, rotational attacks possess the capability to not only ...

Dynamically Discovering Likely Program Invariants to Support Program Evolution
ÐExplicitly stated program invariants can help programmers by identifying program properties that must be preserved when modifying code. In practice, however, these invariants are...

A theory of phase-sensitive rotation invariance with spherical harmonic and moment-based representations
This paper describes how phase-sensitive rotation invariants for three-dimensional data may be obtained. A “bispectrum” is formulated for rotations, and its properties are der...

Two-Dimensional Polar Harmonic Transforms for Invariant Image Representation
This paper introduces a set of 2D transforms, based on a set of orthogonal projection bases, to generate a set of features which are invariant to rotation. We call these transforms...
