Automatic recognition of multiple targets with varying velocities using quadratic correlation filters and Kalman filters

A Rodriguez, J Panza, BVKV Kumar… - 2010 IEEE Radar …, 2010‏ - ieeexplore.ieee.org
Automatic target recognition (ATR) systems require detection, recognition, and tracking
algorithms. The classical approach is to treat these three stages separately. In this paper, we …

Clutter performance and confuser rejection on infrared data using distortion-invariant filters for ATR

R Patnaik, D Casasent - Automatic Target Recognition XVIII, 2008‏ - spiedigitallibrary.org
We consider automatic target recognition (ATR) in infrared (IR) imagery using the minimum
noise and correlation energy (MINACE) distortion-invariant filter (DIF). As in our prior work …

[كتاب][B] Optimal classifier ensembles for improved Biometric Verification

K Venkataramani - 2007‏ - Citeseer
In practical biometric verification applications, we expect to observe a large variability of
biometric data. Single classifiers have insufficient accuracy in such cases. Fusion of multiple …

Minace filter infrared target tracking, recognition, and rejection tests with aspect view, depression angle, and scale variations

R Patnaik, D Casasent - Automatic Target Recognition XVII, 2007‏ - spiedigitallibrary.org
We examine the sensitivity of minimum noise and correlation energy (MINACE) filters to
three different types of distortion variations (aspect view, depression angle, and scale) that …

Distortion-invariant kernel filters for general pattern recognition

R Patnaik, D Casasent - Optical Pattern Recognition XIX, 2008‏ - spiedigitallibrary.org
We note several key general pattern recognition (GPR) issues that have been ignored in all
prior distortion-invariant kernel filter (kernel DIF) work. These include: the unrealistic …

Automatic target recognition performance losses in the presence of atmospheric and camera effects

X Chen, NA Schmid - Journal of Electronic Imaging, 2010‏ - spiedigitallibrary.org
The importance of networked automatic target recognition systems for surveillance
applications is continuously increasing. Because of the requirement of a low cost and limited …

A new SVM for scale, aspect, and depression angle tolerant IR object recognition

YCF Wang, D Casasent - Optical Pattern Recognition XVIII, 2007‏ - spiedigitallibrary.org
In most ATR applications, objects are not only present with thermal and aspect view angle
variations, its size (range) also changes as the sensor approaches the target, and …

Phenomenological modeling of surface roughness for predicting reflection from targets

LB Wolff - Automatic Target Recognition XVII, 2007‏ - spiedigitallibrary.org
Exact wave theories of specular reflectance from rough surfaces are computationally
intractable thus motivating the practical need for geometric reflectance models which treat …
