The author describes a new approach for matching the three-dimensional primitives extracted from a range image with three-dimensional model descriptions in a database. This matching technique is insensitive to primitives either missed or added incorrectly when extracted from the range image. The technique is robust in the presence of noise and can cope with scenes containing occluded objects. The matching algorithm is developed and tested on a scene containing polyhedra.

A method for segmenting stacked seismic data into zones of common signal character based on texture analysis is described. Its performance is demonstrated on a line of seismic data from the Gulf of Mexico that had been manually segmented. The segmentation method uses statistics determined by examining the run-length of seismic reflection events. The run-length method is extended, through a decision process called the RESOLVER, to incorporate heuristic rules to influence the segmentation. The algorithm that applies these constraint rules is similar to rule-based search methods commonly used in artificial intelligence applications. A comparison is made between the automatic segmentations of the section and a manual interpretation.

A systolic array is a natural architecture for a high-performance signal processor, in part because of the extensive use of inner-product operations in signalprocessing. The modularity and simple interconnection of systolic arrays promise to simplify the development of cost-effective, high-performance, special-purpose processors. ESL Incorporated has built a proof of concept model of a systolic processor. It is flexible enough to permit experimentation with a variety of algorithms and applications. ESL is exploring the application of systolic processors to image- and signal-processing problems. This paper describes this experimental system and some of its applications to signalprocessing. ESL is also pursuing new types of systolic architectures, including the VLSI implementation of systolic cells for solving systems of linear equations. These new systolic architectures allow the real-time design of adaptive filters.

This paper presents a sequency spectrum for the discrete cosine transform (DCT) which has recently found application in the area of signalprocessing, (e.g. imageprocessing) [1],[2] The basis vectors of the DCT are essentially "amplitude modulated" versions of the Walsh/sequency-ordered Walsh-Hadamard transform (WHT)
w.
Consequently there is a one-to-one correspondence between the sequencies of the sal-cal functions of the (WHT)w and their counterparts of the DCT. It is shown that this correspondence leads to the definition of a sequency power spectrum for the OCT. This definition is analogous to the (WHT)
w
spectrum, i.e. the power carried by the sal and cal components. An analogous phase spectrum is also defined. The DCT power spectrum properties are illustrated by means of examples and compared with corresponding Walsh and Fourier spectra. [1] ***, ***: Orthogonal Transforms for Digital signalprocessing.

The Optical Society of America conference on applications of High Fields and Short Wavelength Sources, held in Santa Fe, New Mexico, USA, from March 20-22, 1997, was an exceptionally exciting conference. This conference was the seventh in a series of topical con ferences, held every two years, which are devoted to the generation and application of high field and short wavelength sources. The meeting was truly international in scope, with equal participation from both within and outside of the US. In the past two years, there has been dramatic progress in both laser and x-ray coher ent sources, both fundamental and applied. The 1997 meeting highlighted these advances, which are summarized in sections 1 and 2 of this volume. Terawatt-class lasers are now avail able in the UV or at high repetition rates. Michael Perry (LLNL) presented a keynote talk on petawatt class lasers and their applications in inertial confinement fusion, while Jorge Rocca (Colorado State University) presented a keynote talk on tabletop soft-x-ray lasers. Genera tion and measurement techniques are becoming very sophisticated throughout the UV and x ray region of the spectrum, and coherent sources have been extended to wavelengths below 30A. Phase control in the x-ray region is also now possible, and new phase-matching schemes in the UV have been experimentally demonstrated. It is clear that a new field of x-ray nonlin ear optics will deveiop rapidly over the next few years.

It is probably true quite generally that in the history of human thinking the most fruitful developments frequently take place at those points where two different lines of thought meet. Hence, if they actually meet, that is, if they are at least so much related to each other that a real interaction can take place, then one may hope that new and interesting developments may follow. Werner Heisenberg This volume contains papers presented at the August 1992 NATO Advanced Study Institute on wavelets and Their applications. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. Once again we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usu ally disparate communities of pure mathematicians and applied scientists, which occurred at our 1989 and 1991 ASI's, continued at this meeting. Wavelet theory and technology is in an important growth stage at which theoretical and practical results are being compared with existing methods. There have been spectacular wavelet successes and sobering comparisons with traditional ideas-but still there is a wide expanse of scientific problems to explore. Since these problems lie at the forefront of both pure mathematics and applied science, our NATO ASI was especially pertinent at this time.
