Nonlinear image processing using teager filters

Summary form only given, as follows. Two-dimensional quadratic Voleterra operators developed for edge enhancement are reviewed. A number of practical image processing applications of these - Iters are then considered and the proposed algorithms are outlined. These applications include image contrast enhancement, impulse noise removal, image zooming, and image half-toning. 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.
