Mathematical morphology, developed in the early 1960's for
single-component signals, has been applied to a number of image
processing applications. This investigation examines the systematic
extension of mathematical morphology to multi-variate signals.
Two approaches are considered. The first approach, the
extension of the theory of single-component morphological filters to
multi-variate...
Machine vision is widely used in scientific areas and non-wood using
industries, but the extreme variability of wood has limited its adoption by forest
products industries. However, it is now becoming a key factor in further automation
of the forest products industry. As a very important part of machine vision,...
Multiport network functions, such as impedance matrix
parameters and scattering parameters, of general multiple
coupled slab waveguides are derived in terms of the normal
mode parameters of the system. These characteristic normal
mode parameters include the propagation constants, the
modal impedances, and the eigenvector matrices. It is
shown that the...
A new CAD-oriented methodology for the full-wave broadband characterization of coupled microstrip structures for RF/microwave and high-speed digital circuits is presented. The characterization methodology is based on the finite difference time domain (FDTD) technique combined with a systematic extraction procedure using the normal mode approach and multiport network concepts. The...
