Efficient Nonlinear Image Processing Algorithms
Professor Sanjit K. Mitra
University of California, Santa Barbara, California


Two-dimensional quadratic Voleterra operators developed
for edge enhancement are reviewed. A number of practical image
processing applications of these filters are then considered and the
proposed algorithms are outlined. These applications include image
contrast enhancement, impulse noise removal, image zooming, image
half-toning, and image coding. In each of these applications, it is
shown that the processed images appear perceptually much better in
quality than those obtained using many other well-known methods.
