Overview
The prevalence of various data processing technologies and high-end computers has enabled the ability to mathematically manipulate data which has formerly relied on the brain for processing such as speech, audio, images, and video. This area has four faculty members, and research and teaching in this area are on fundamental theory and applications to real-world data processing problems. Data processing touches a large variety of engineering problems, from communication to human-computer interface, to medical imaging and multimedia.

Research
Research in this area at OSU includes the following three main thrusts — (1) Signal processing: audio compression, speech recognition, speech synthesis, language identification, statistical signal processing, wireless sensor networks. (2) Image processing: image compression, image enhancement, remote sensing data analysis, medical image analysis. (3) Video processing: content-based video analysis, visual surveillance, human activity recognition, object tracking/recognition, and multimedia applications, etc.
