The ability to learn about a stochastic process from noisy observations is fundamental to many applications. In order to track a dynamic process, typical knowledge representation is the state space model such as a linear Gauss Markov model, where efficient algorithms exist to perform state estimation under many different model assumptions. However, for meta level tracking, we are not only interested in the state estimation, but also temporal and structural classification of the process.

Polarimetric Synthetic Aperture Radar (POLSAR) data is an important source for many operational remote sensing applications. Segmentation and classification of image data are important tasks for POLSAR data analysis and interpretation, which often requires human interaction. In this thesis, spectral graph partitioning methodology is used to exploit both the polarimetric attributes of pixels, and the visual aspect of the image data through visual cues.

Synthetic attendance--immersive communications with people in a meeting happening afar--has been one of mankind's elusive dreams. The Exploratory DSP column of the IEEE Signal Processing Magazine (November 2009) discusses critical questions in immersive communications that are still awaiting resolution.

Signal processing engineers usually use high level languages to develop advanced algorithms for new radars and to determine the optimal parameters for these algorithms. The long execution times due to computational complexity and/or very large data sets hinders an efficient engineering development workflow. Rapid prototyping tools such as parallel MATLAB can enable a software design workflow that helps the development of radar prototypes by providing interactivity and reducing the execution time of the algorithms under test.

As the field of digital forensics has continued to grow, a central repository of Digital Forensic Database (DFD) is being created to help researchers, practitioners, and students keep track of published papers in this area.
The DFD maintains a bibliography for technical papers in the field of digital forensics, and allows for a variety of search capabilities.
