Title: Information-theoretic measures of hyperspherical harmonics

Abstract

The multidimensional spreading of the hyperspherical harmonics can be measured in a different and complementary manner by means of the following information-theoretic quantities: the Fisher information, the average density or first-order entropic moment, and the Shannon entropy. They give measures of the volume anisotropy of the eigenfunctions of any central potential in the hyperspace. Contrary to the Fisher information, which is a local measure because of its gradient-functional form, the other two quantities have a global character because they are powerlike (average density) and logarithmic (Shannon's entropy) functionals of the hyperspherical harmonics. In this paper we obtain the explicit expression of the first two measures and a lower bound to the Shannon entropy in terms of the labeling indices of the hyperspherical harmonics.

  • The purpose of this study was to evaluate image similarity measures employed in an information-theoretic computer-assisted detection (IT-CAD) scheme. The scheme was developed for content-based retrieval and detection of masses in screening mammograms. The study is aimed toward an interactive clinical paradigm where physicians query the proposed IT-CAD scheme on mammographic locations that are either visually suspicious or indicated as suspicious by other cuing CAD systems. The IT-CAD scheme provides an evidence-based, second opinion for query mammographic locations using a knowledge database of mass and normal cases. In this study, eight entropy-based similarity measures were compared with respect to retrievalmore » precision and detection accuracy using a database of 1820 mammographic regions of interest. The IT-CAD scheme was then validated on a separate database for false positive reduction of progressively more challenging visual cues generated by an existing, in-house mass detection system. The study showed that the image similarity measures fall into one of two categories; one category is better suited to the retrieval of semantically similar cases while the second is more effective with knowledge-based decisions regarding the presence of a true mass in the query location. In addition, the IT-CAD scheme yielded a substantial reduction in false-positive detections while maintaining high detection rate for malignant masses.« less
  • The hyperspherical harmonics which appear in the analysis of the planar three-body problem are explicitly expressed in terms of the harmonics of importance in the theory of magnetic monopoles. This connection is achieved by transforming the eigenvalue equations which define hyperspherical harmonics into the eigenvalue equations for monopole harmonics. This transformation requires the recognition of a gauge potential which arises in the three-body problem and which has the same form as that of a magnetic monopole. In this manner, explicit formulas for the two standard representations of the three-body harmonics are derived. The coupling coefficients between the two representations followmore » naturally from the derivation. Emphasis is placed on the gauge theoretical aspects of the derivations and the significance of gauge transformations is discussed. {copyright} {ital 1997} {ital The American Physical Society}« less
