چکیده

It is well-known that an image can be reconstructed from an infinite set of moments. Many works have focused on the reconstruction aspects of orthogonal moments, and have shown that the image can be reconstructed easily from a finite set of orthogonal moments. However, reconstruction ability of geometric moments is not yet proved. In this paper, the inverse problem of geometric moments is addressed. The approach used consists in recovering the Fourier transform of the image from the geometric moments set. Then, the image is reconstructed using the inverse Fourier transform. Both theoretical and experimental results are given.

A Novel Symmetry-based Method for Efficient Computation of 2d and 3d Geometric Moments

Moment invariants are widely used in reconstruction, recognition and discrimination of 2D and 3D images. Accurate and efficient computation of these moment invariants is a big challenge to the community of image processing and pattern recognition. Since the wide class of moment invariants of digital images is generally expressed as a combination of geometric moments, highly accurate and efficie...

Reconstructing Archeological Vessels by Fusing Surface Markings and Border Anchor Points on Fragments

This paper presents a method to assist in the tedious process of reconstructing ceramic vessels from excavated fragments. The method exploits vessel surface marking information (models) supplied by the archaeologists along with anchor points on the fragment borders for reconstruction. Marking models are based on expert historical knowledge of the period, provenance of the artifact, and site loc...

Image analysis using moments

Moments of images provide efficient local descriptors and have been used extensively in image analysis applications. Their main advantage is their ability to provide invariant measures of shape. In this work, we present an overview of the most commonly used image moments, as well as a hardware architecture capable of fast calculation of geometric, Zernike and Tchebichef moments. Index Terms – I...

Exact and fast computation of geometric moments for gray level images

Geometric moments are widely used in image processing and pattern recognition. While several methods have been proposed, exact geometric moment’s computation for gray level images is still unavailable. In this paper exact values of geometric moments are calculated using mathematical integration of the monomial terms over digital image pixels. This method removed the numerical approximation erro...

In the frame work of relativistic density functional theory, using full potential local orbital band structure scheme (FPLO), the magnetic properties of single 3d transition metals (3d-TM) adsorbed on 2D hexagonal boron nitride (2D h-BN) are investigated. Binding energies between 3d-TM adatoms and 2D h-BN in three different compositions, local spin magnetic moments of 3d-TM and total spin magne...
