Advanced filters are described for distortion-invariant space-invariant object identification and location in clutter using correlators. These correlation synthetic discriminant functions (SDFs) are extensions of earlier projection SDFs. They provide control of the sidelobe levels and the shape of the output correlation function as well as its peak intensity. The theory for synthesis of three such SDFs and a discussion of correlation plane detection criteria for use with these filters are presented.

On the development of an objective flow regime indicator

We present efficient parallel matrix multiplication algorithms for linear arrays with reconfigurable pipelined bus systems (LARPBS). Such systems are able to support a large volume of parallel communication of various patterns in constant time. An LARPBS can also be reconfigured into many independent subsystems and, thus, is able to support parallel implementations of divide-and-conquer computations like Strassen's algorithm. The main contributions of the paper are as follows. We develop five matrix multiplication algorithms with varying degrees of parallelism on the LARPBS computing model; namely, MM/sub 1/, MM/sub 2/, MM/sub 3/, and compound algorithms C/sub 1/(/spl epsiv/)and C/sub 2/(/spl delta/). Algorithm C/sub 1/(/spl epsiv/) has adjustable time complexity in sublinear level. Algorithm C/sub 2/(/spl delta/) implies that it is feasible to achieve sublogarithmic time using /spl sigma/(N/sup 3/) processors for matrix multiplication on a realistic system. Algorithms MM/sub 3/, C/sub 1/(/spl epsiv/), and C/sub 2/(/spl delta/) all have o(/spl Nscr//sup 3/) cost and, hence, are very processor efficient. Algorithms MM/sub 1/, MM/sub 3/, and C/sub 1/(/spl epsiv/) are general-purpose matrix multiplication algorithms, where the array elements are in any ring. Algorithms MM/sub 2/ and C/sub 2/(/spl delta/) are applicable to array elements that are integers of bounded magnitude, or floating-point values of bounded precision and magnitude, or Boolean values. Extension of algorithms MM/sub 2/ and C/sub 2/(/spl delta/) to unbounded integers and reals are also discussed.

Fast and processor efficient parallel matrix multiplication algorithms on a linear array with a reconfigurable pipelined bus system

This paper discusses short-distance optical interconnects for general-purpose distributed digital systems. We describe the technology required to optically interconnect elements that are distributed across multiple packaging layers. This includes chips on a board, boards in a backplane, and shelves within a bay. The focus of this paper will be on technology capable of supporting high-data-rate, two-dimensional, optical communication using two-dimensional parallel optical interconnects.

Optical interconnects at the chip and board level: challenges and solutions

H J Caulfield (ed) 1979 New York: Academic xiv + 638 pp price $55 This book is for people who want to use holography. It is intended as a reference work but has a textbook approach which makes it enjoyable to read and the 31 authors who have contributed to ten chapters have achieved in one manageable volume a good up to date account of optical holography, its practice and applications.

Matched filtering is the key concept in coherent optical pattern recognition. Unfortunately, matched filters are more
sensitive to some things (nonconsequential variations in size, rotation angle, etc.) and less sensitive to other things
(differences between object classes) than we might desire. The generalized matched filter is a filter tailored to the
specific requirements of the task. It contains the matched filter as a special case.

Matched filtering is often too sensitive to within-class variations (rotation, translation, magnification, etc.) and too insensitive to between-class variations. Improvements can be sought by changing the input, changing the filter, or changing the way the data is handled. We review both systematic and ad hoc methods to accomplish those improvements. The resulting improvements make coherent optical pattern recognition far more versatile in 1980 than it was when it began in 1964.
