Studies in Signal Processing with Applications

Digital signal processing (DSP) techniques have found a variety of applications over the last 30 years in processing of signals in such diverse areas as biomedical signal processing, acoustics, telecommunications, image and video signal processing, and seismology. The availability of high-resolution, inexpensive, high-speed A/D converters and powerful digital signal processors in VLSI form has provided the necessary impetus for the ever-expanding applications of DSP in these areas. Multi-dimensional DSP techniques are being increasingly used in the processing of multi-dimensional signals such as pictures and moving pictures obtained from satellites, x-rays, and other sources. Videophone and HDTV are some examples of products that have gained from the research and development advances in the 2-D and 3-D DSP area. The overall objectives of the proposed research are to develop a variety of efficient and reliable algorithms for filtering and processing of signals (such as image, video, speech, and biomedical signals). In particular, we will concentrate over the next 5 years on the following projects.
