Digital Signal Processing is a monthly peer-reviewed open access scientific journal covering all areas of signal processing. It as established in 1991 and published by Academic Press, now Elsevier. The editor-in-chief is Ercan E. Kuruoglu (ISTI-CNR, Pisa, Italy).
Lenna (or Lena) is a standard test image used in the field of digital image processing, starting in 1973. [1] It is a picture of the Swedish model Lena Forsén , shot by photographer Dwight Hooker and cropped from the centerfold of the November 1972 issue of Playboy magazine.
Digital signal processing (DSP) is the study of signals in a digital representation and the processing methods of these signals. DSP and analog signal processing are subsets of signal processing . It has three major subfields: audio signal processing , digital image processing and speech processing .
Digital signal processing is the processing of digitized discrete-time sampled signals. Processing is done by general-purpose computers or by digital circuits such as ASICs , field-programmable gate arrays or specialized digital signal processors .
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone ...
Processing digital signals, particularly multidimensional signals, often involves a series of vector operations on massive numbers of independent data samples, GPGPUs are now widely employed to accelerate multidimensional DSP, such as image processing, video codecs, radar signal analysis, sonar signal processing, and ultrasound scanning.
He is known for his research and teaching in the general area of digital signal processing and image and video processing in particular. He is the author of more than 240 publications, 15 books and 16 patents. He played a pioneering role in digital image and video compression. Among the 75 doctoral students he supervised, 20 are now university ...
