Dr. Mohammad S. Alam, professor and chair of the University of South Alabama’s department of electrical and computer engineering, presented 10 technical papers at the 2007 SPIE Defense and Security Symposium in Orlando, Fla. Nine of the papers were co-authored by USA graduate students and postdoctoral research associates in the department.

SPIE is the International Society for Optical Engineering, and its Defense and Security Symposium is the largest, unclassified international symposium related to sensors and sensor networks. Its goal is to eliminate barriers for engineers and scientists who are developing and utilizing electro-optical, digital, and microwave technologies for sensor-related defense and security applications.

Alam presented the following papers at the symposium:

• “Pattern Recognition in Hyperspectral Imagery Using Gaussian Filter with Post-Processing” (invited paper), co-authored by Dr. Abdullah Bal of the Yildiz Technical University and Dr. Nazrul Islam of the University of West Florida


• "Super-Resolution Reconstruction of Hyperspectral Images," co-authored by postdoctoral research associate Dr. M. Ibrahim Elbakary


• "Hyperspectral Target Detection by Using Independent Component Analysis-Based Linear Mixing Model," co-authored by postdoctoral research associate Dr. Erol Sarigul


• "Object Detection in Hyperspectral Imagery Using K-Means Clustering Algorithm with Pre-Processing," co-authored by Elbakary and graduate student Melih Aslan


• "Fast Implementation of N-FINDR Algorithm for Endmember Determination in Hyperspectral Imagery," co-authored by graduate student Amar Chowdhury


• "Target Detection in High-Dimensional Space Using a Stochastic Expectation Maximization Algorithm," co-authored by Elbakary and graduate student Mahmut Karakaya


• "Pattern Recognition in Hyperspectral Imagery Using One-Dimensional MACH Filter and Mahalanobis Distance," co-authored by graduate student M. Faysal Islam


• "Nonlinear Unmixing of Hyperspectral Data Using BDRF and Maximum Likelihood Algorithm," co-authored by graduate student Tayabur Rahman


• "Human Motion Tracking Using Mean Shift Clustering and Discrete Cosine Transform," co-authored by graduate student M. Moinul Islam


• "An Automated Method for Pattern Recognition Using Linear Mixing Model and Vertex Component Analysis," co-authored by Sarigul

Alam also served as a member of the panel on Automatic Target Recognition and chaired the session on Pattern Recognition and Processing at the conference.

At the 2006 SPIE conference, Dr. Aed El-Saba, associate professor in the department of electrical and computer engineering at USA, presented a paper on "High Performance Polarization-Enhanced Wavelet Joint Transform Correlation for Automatic Target Recognition System." The paper was co-authored by Alam and graduate student Harikiran Nalluri.
