This book contains the proceedings of the NATO Advanced Research
Workshop held in Maratea (Italy), May 5-9, 1986 on Pyramidal
Systems for Image Processing and Computer Vision. We had 40
participants from 11 countries playing an active part in the
workshop and all the leaders of groups that have produced a
prototype pyramid machine or a design for such a machine were
present. Within the wide field of parallel architectures for image
processing a new area was recently born and is growing healthily:
the area of pyramidally structured multiprocessing systems.
Essentially, the processors are arranged in planes (from a base to
an apex) each one of which is generally a reduced (usually by a
power of two) version of the plane underneath: these processors are
horizontally interconnected (within a plane) and vertically
connected with "fathers" (on top planes) and "children" on the
plane below. This arrangement has a number of interesting features,
all of which were amply discussed in our Workshop including the
cellular array and hypercube versions of pyramids. A number of
projects (in different parts of the world) are reported as well as
some interesting applications in computer vision, tactile systems
and numerical calculations.
This book offers readers a broad view of research in some Western
and Eastern European countries on pattern and signal analysis, and
on coding, handling and measurement of images. It is a selection of
refereed papers from two sources: first, a satellite conference
within the biannual International Conference on Pattern Recognition
held in Rome, November 14-17, 1988, and second, work done at the
International Basic Laboratory on Image Processing and Computer
Graphics, Berlin, GDR. The papers are grouped into three sections.
The first section contains new proposals for the specific
computation of particular features of digital images and the second
section is devoted to the introduction and testing of general
approaches to the solution of problems met in digital geometry,
image coding, feature extraction and object classification. The
third section illustrates some recent practical results obtained on
real images specifically in character and speech recognition as
well as in biomedicine. All the techniques illustrated in this book
will find direct application in the near future. This book should
interest and stimulate the reader, provoke new thoughts and
encourage further research in this widely appealing field.
Artificial Vision is a rapidly growing discipline, aiming to build
computational models of the visual functionalities in humans, as
well as machines that emulate them. Visual communication in itself
involves a numberof challenging topics with a dramatic impact on
contemporary culture where human-computer interaction and human
dialogue play a more and more significant role.
This state-of-the-art book brings together carefully selected
review articles from world renowned researchers at the forefront of
this exciting area. The contributions cover topics including image
processing, computational geometry, optics, pattern recognition,
and computer science. The book is divided into three sections. Part
I covers active vision; Part II deals with the integration of
visual with cognitive capabilities; and Part III concerns visual
communication.
Artificial Vision will be essential reading for students and
researchers in image processing, vision, and computer science who
want to grasp the current concepts and future directions of this
challenging field.

The exponential explosion of images and videos concerns everybody's
common life, since this media is now present everywhere and in all
human activities. Scientists, artists and engineers, in any field,
need to be aware of the basic mechanisms that allow them to
understand how images are essentially information carriers. Images
bear a strong evocative power because their perception quickly
brings into mind a number of related pictorial contents of past
experiences and even of abstract concepts like pleasure, attraction
or aversion. This book analyzes the visual hints, thanks to which
images are generally interpreted, processed and exploited both by
humans and computer programs.
