This volume stresses the necessity of image processing for future high energy physics detectors (indeed the signals — 1 megabyte of data or more, every 16 nanoseconds — will have 2D-spatial-topology-like images; only the processing/decision rates are much higher). The main issues presented are: new detectors, algorithms for tracking and pattern recognition, dedicated archi-tectures, benchmarking studies on commercially avaliable machines, mixed VLSI technologies, neural networks.
