Digital Signal Processing, Data Compression, Speech, Audio Image Processing. Contour tracing algorithms. Contour tracing is an important image processing task. Many algorithms are available.
Current research is on fast sequential algorithms which handle large bitmaps and open contours.
A table look-up method is under development to assist in the fast chain coding of contours. Cellular mobile and spread spectrum communications. Fiber soliton laser, lightwave network protocols, traffic management of broadband networks, higher order spectra signal analysis.
