Detection of geological lineations on aerial photographs using two-dimensional spectral analysis

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 Polar Harmonic Transforms (PHTs). Unlike the well-known Zernike and ...

Image moment invariants has been widely used in the fields of pattern recognition and computer vision, since they are able to represent pattern features independently of geometric transformations. Currently, Separable Moments and their invariants ...

Quaternions play a vital role in the representation of rotations in computer graphics, primarily for animation and user interfaces. Unfortunately, quaternion rotation is often left as an advanced topic in computer graphics education due to difficulties ...
