Digital signal/image/video processing

Digital signal and image processing is concerned with the digital representation (in the case of continuous real-world analog signals) and processing of signals and images using computers in order to measure, filter or compress them. Digital signal and image processing is used in audio and speech signal processing, biomedical signal processing, sonar and radar signal processing, sensor array processing, spectral estimation, communications signal processing, systems control, seismic data processing, etc.
