Springer, 1986. — 392 p. — ISBN 978-3-642-82940-6.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. 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. The design of pyramidal algorithms, based on primitive operations, on the upward and downward propagation of the information (from base to apex and vice versa) and the possibility of executing digital transforms with pyramids was investigated and may be found in these proceedings as well as image segmentation (based on a model of the visual system), local motion estimation, graphical applications and the detection of vectorial features.Parallel, Hierarchical Software/Hardware Pyramid Architectures I.
