Abu - Mostafa and Psal Tis : Image Normalization
نویسنده
چکیده
The role of moments in image normalization and invariant pattern recognition is addressed. The classical idea of the principal axes is analyzed and extended to a more general definition. The relationship between moment-based normalization, moment invariants, and circular harmonics is established. Invariance properties of moments, as opposed to their recognition properties, are identified using a new class of normalization procedures. The application of moment-based normalization in pattern recognition is demonstrated by experiment.

Supercomplexes of IsiA and photosystem I in a mutant lacking subunit PsaL.
The cyanobacterium Synechocystis PCC 6803 grown under short-term iron-deficient conditions assembles a supercomplex consisting of a trimeric Photosystem I (PSI) complex encircled by a ring of 18 IsiA complexes. Furthermore, it has been shown that single or double rings of IsiA with up to 35 copies in total can surround monomeric PSI. Here we present an analysis by electron microscopy and image ...
متن کاملA Note on a Capacity Result for theHop eld Neural Network
In this note we prove, by using straightforward arguments, a stronger version of a well-known capacity result proved by Abu-Mostafa and St. Jacques. Our results states that no Hoppeld memory can have a \capacity" (in Abu-Mostafa and St. Jacques's sense) exceeding 1, thereby showing the inadequacy of their capacity notion.
متن کاملComparison of Count Normalization Methods for Statistical Parametric Mapping Analysis Using a Digital Brain Phantom Obtained from Fluorodeoxyglucose-positron Emission Tomography
Objective(s): Alternative normalization methods were proposed to solve the biased information of SPM in the study of neurodegenerative disease. The objective of this study was to determine the most suitable count normalization method for SPM analysis of a neurodegenerative disease based on the results of different count normalization methods applied on a prepared digital phantom similar to one ...
