Multiprocessor computing for images

A review of image-processing systems developed until now is given, highlighting the weak points of such systems and the trends that have dictated their evolution through the years producing different generations of machines. Each generation may be characterized by the hardware architecture, the programmability features and the relative application areas. The need for multiprocessing hierarchical systems is discussed, focusing on pyramidal architectures. Their computational paradigms, their virtual and physical implementation, their programming and languages, are discussed
