IM: An R-Package for Computation of Image Moments and Moment Invariants. (arXiv:2210.16485v1 [cs.CV])

Moment invariants are well-established and effective shape descriptors for
image classification. In this report, we introduce a package for R-language,
named IM, that implements the calculation of moments for images and allows the
reconstruction of images from moments within an object-oriented framework.
Several types of moments may be computed using the IM library, including
discrete and continuous Chebyshev, Gegenbauer, Legendre, Krawtchouk, dual Hahn,
generalized pseudo-Zernike, Fourier-Mellin, and radial harmonic Fourier
moments. In addition, custom bivariate types of moments can be …
