Key issues about extraction of target character in creation of IR image environment is studied. It presents a multi stage data flow that consists of three level functional modules, which are adaptive background perception and subtracting operation, selection of automatic threshold used for clutter suppression, shape analyzing and target character recognition.
The article analyzed the requirement of spot shape design in traditional camouflage theory, and pointed out some problems. Then, combining shape analyzing theory of modern image processing, the article brought forward the vector that is composed of area, girth, dispersing ratio, elongation ratio and whole concavity as feature vector to describe spot shape, and different requirements of spot shape design for big and small targets.
A Statistical Method of Pulse Shape Analysis and Its Application to Nuclear Spectroscopy
The line shape analysis confirmed the presence of a spatially modulated, incommensurate cycloidal spin structure in BiFeO3 and allowed the actual spin distribution to be reproduced throughout the cycloid length.
Spectral-peak-shape analysis demonstrates the high hydrophilicity of hydrogenated single-walled carbon nanotubes, whereas the sorption of atmospheric oxygen is insignificant as compared with the sorption of water.
A discussion is given of background reduction by material selection, detector segmentation, pulse shape analysis, and electroformation of copper parts and granularity.
Multi-sensor image registration using multi-resolution shape analysis
In this study, closed-form analysis method considering the effect of girder deflection is developed, based on the elastic plate theory.
A normal-form analysis is presented which shows that the boundary-value problem can be reduced to an integrable system of ordinary differential equations plus a remainder term containing nonlocal terms of higher order for |μ| small.
For the description of this effect, a closed-form analysis is presented.
Comparison to respective finite element analysis gives good agreement, and validates the presented closed-form analysis as very useful.
