The Euclidean distance transform (EDT) is an important tool in image analysis. Previous work on computation of EDT is limited to sequential algorithms and parallel algorithms on general purpose architectures. The authors develop a fast parallel algorithm that is amenable for VLSI implementation. The VLSI architecture is presented. Results of implementation of the VLSI design in a commercial package are also presented, and confirm the speed and suitability of the new method for real-time applications.

Optical signal processing (OSP) offers numerous advantages in real time imageprocessing applications. OSP inherently offers parallelism in the processing of data at speeds much higher than those achievable using electrical digital signal processing (DSP). In this contribution a review of the available OSP techniques for imageprocessing is given. Particular attention is given to image feature estimation in background noise while the necessary OSP implementations are demonstrated.

An imageprocessing system based upon Texas Instruments TMS320C40 digital signal processors is described, which is currently in the final stages of development and will be applied to non-contact inspection of medical and industrial applications. The system is capable of manipulating HDTV resolution images and is due to be operational during the second quarter of 1994.

The paper introduces the generalised hierarchical massively parallel system (MPS) and extends data transfer parallelism to all members of the memory hierarchy. Methods are presented for connecting multiple parallel disks and parallel memory modules to the generalised hierarchical MPS. Full utilisation of data transfer bandwidth between disks and processing elements is facilitated by structuring and corner turning the incoming data before storing it on parallel disks. One major application of MPSs is imageprocessing. The methods presented perform well on image data. The total system is generalised by introducing architectural parameters. Varying these parameters allows the system to be represented as various forms of SIMD architecture. A new SIMD massively parallel system, BLITZEN, is used as an example to illustrate some of the concepts presented.

Several important parameters must be considered in the implementation and specification of high performance algorithms for pattern classification. These include the use of appropriate parallelprocessing computational infrastructure and techniques which allow effective pattern rejection and decision making during the early stages in the processing chain. Several techniques for such applications are presented in this paper.

image reconstruction by computer tomography provides a nonintrusive method of imaging the internal structure of objects. From measurements of radiation (e.g. X-rays or gamma rays) passed through an object, it is possible to reconstruct the internal structure. There is great interest in the potential of such methods in industrial applications but a number of problems need to be solved before these opportunities can be realised. The reconstruction process is computationally intensive and requires imaginative parallelprocessing algorithms to attain ‘real-time’performance. The work carried out has involved evaluating how these algorithms can be used in multiprocessor concurrent architectures to obtain rapid image reconstruction. A suitable computer architecture has been simulated in occam. This allows execution on a collection of transputers.
