Moment Shape Feature
Jyotismita Chaki, Nilanjan Dey · 2019
This chapter provides an overview of moment-based shape feature extraction techniques. Both the contour based and region based moment descriptors are discussed in this chapter. Different methods to extract moment shape feature including contour, geometric invariant, Zernike, radial Chebyshev, Legendre, homocentric polar-radius, orthogonal Fourier-Mellin and pseudo-Zernike are discussed in this chapter. The benefits and limitations of each method are also discussed. All the techniques are represented in such a way that they will be easy to understand for those who are new to the research field as most of the techniques are described with equations and pictorial representations.
