✦ Synopsis

This special issue on CNN addresses three areas: theory, design, and applications. It is clear from the table of contents that most of the advances reported here are, explicitly or tacitly, influenced by the existence of the programmable CNN universal machine chips. A new programming discipline, the analogic CNN algorithmic thinking, is emerging where the elementary instruction is a non-linear spatiotemporal operator defined by a CNN cloning template. Circuit theory, systems aspects, and algorithm design are developing hand-inhand.

In the Theory section, the realizability of large neighbourhood templates on 3;3 neighbourhood machines, as well as a unified characterization of multilayer higher-order CNN are presented. In addition to these, the synthesis of three types of operators are presented: (i) arbitrary local Boolean functions, (ii) invertible Boolean operators, and (iii) patterns and autowaves.

In the section on Design the formulation of the 'art' of template design is presented for propagating binary operators, including the famous connectivity problem, an analogic CNN algorithmic frame is presented for stereo problems, and a CAD environment is described for the VLSI CNN chip designer. Robustness is a key issue when implementing algorithms on CNN Universal programmable chips. The two papers in this area cover the theoretical as well as the practical aspects.

The main theme of the Applications section is video coding and analysis of noisy motion pictures. In addition, a layout error detection algorithm is presented.

Physical implementation, including computing infrastructure, and the biologically inspired aspects are not covered in this special issue. These areas are, however, the main themes of a companion special issue in the IEEE Transactions on Circuits and Systems.
