Bio

Alexander C. Loui received his B.A.Sc. (Honors), M.A.Sc, and Ph.D. all in Electrical Engineering from the University of Toronto, Canada. He is a Professor of Practice in the Department of Computer Engineering at Rochester Institute of Technology, and leads the Multimodal Analysis and Perception (MAP) Lab. Prior to that, he spent over 28 years in a number of technical and research leadership positions with Kodak Alaris (2013-18), Kodak Research Labs (1996-13), and Bell Communications Research (1990-96). Dr. Loui has been directing research and algorithm development on computer vision, image/video processing and analysis, video summarization, image management, and visual communications. His research interests also include machine learning and data mining algorithms for multimedia and AI applications. He has published over 100 refereed journal and conference papers and has been granted over 95 US patents in these areas.

Dr. Loui is a Senior Area Editor of IEEE Transactions on Image Processing, and a Senior Editor of SPIE/IS&T Journal of Electronic Imaging. He had served as an associate editor of IEEE Transactions on Circuits and Systems for Video Technology and IEEE Transactions on Multimedia. He had been an elected member of the IEEE ICME Steering Committee, IVMSP, MMSP, and MSA Technical Committees. He was Chair of the IEEE Rochester Section (2010-11), and Chair of the Rochester Chapter of IEEE Signal Processing Society (2005). Dr. Loui was named a Kodak Distinguished Inventor for his contributions to image understanding and management technologies. He is a recipient of the IEEE Region 1 Technological Innovation Award and a Fellow of IEEE and SPIE.

Currently Teaching

CMPE-480
Digital Signal Processing
3 Credits
This course introduces the basic elements of continuous and discrete time signals and systems and fundamental signal processing techniques, such as FIR and IIR Filtering, the Fourier transform, the Discrete Fourier transform and the z transform. Theory is strengthened through MATLAB-based projects and exercises.
CMPE-497
Multidisciplinary Senior Design I
3 Credits
This is the first in a two-course sequence oriented to the solution of real-world engineering design problems. This is a capstone learning experience that integrates engineering theory, principles, and processes within a collaborative environment. Multidisciplinary student teams follow a systems engineering design process, which includes assessing customer needs, developing engineering specifications, generating and evaluating concepts, choosing an approach, developing the details of the design, and implementing the design to the extent feasible, for example by building and testing a prototype or implementing a chosen set of improvements to a process. This first course focuses primarily on defining the problem and developing the design, but may include elements of build/ implementation. The second course may include elements of design, but focuses on build/implementation and communicating information about the final design.
