  • Recognition of partially occluded two-dimensional objects

    Publication Year: 1987

    Recognition of partially occluded objects is essential for many industrial applications of machine vision. A fast and reliable algorithm based on subtemplate matching of boundary images is proposed to tackle the problem. Dynamic programming (DP) is employed in the algorithm to ensure an optimal consistent solution. With the weightings of the subtemplate determined off-line, the computational effor...

  • Arithmetic unit with integral division and square root

    Publication Year: 1987, Page(s):17 - 23
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (790 KB)

    Arithmetic units are usually designed to perform addition and subtraction as quickly as possible, with multiplication as a good second. Division is sometimes added later, and a few workers have proposed hardware for other mathematical functions. The paper describes an attempt to design a combined division and square-root unit, drawing on the similarities of algorithm to be seen in comparing the pe... View full abstract»

  • Partitioning concurrent VLSI simulation programs onto a multiprocessor by simulated annealing

    Publication Year: 1987, Page(s):24 - 30
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (859 KB)

    Efficiently loading concurrent programs onto multiprocessor architectures is a graph partitioning problem where both the edges and vertices are weighted. The corresponding optimisation problem is computationally NP-hard, and the optimal solution can only be found by exhaustively examining all possible partitioning configurations. Near-optimal solutions can be found by using heuristic algorithms su... View full abstract»

  • Real-time shaded colour polygon generation system

    Publication Year: 1987, Page(s):31 - 38
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (975 KB)

    The paper describes a hardware architecture for a graphics system which can generate shaded, colour, perspective 2-dimensional images of complex 3-dimensional scenes, in real time. The architecture is capable of operating at the high pixel rates required to produce scenes on rasterscan displays with high spatial resolution (1280 H by 1024 V), high colour resolution (24-bit), and high refresh rate ...

  • RAPAC: a high-speed image-processing system

    Publication Year: 1987, Page(s):39 - 46
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (987 KB)

    The paper describes the design and operation of a real-time image processing system and outlines one of its application areas. The system consists of a dedicated hardware processor called RAPAC (a reconfigurable attached processor architecture for convolution) and a host computer which is used for algorithm development and RAPAC control. RAPAC uses hardware processor units and multiple image memor... View full abstract»

  • Ethernet for real-time applications

    Publication Year: 1987, Page(s):47 - 53
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (857 KB)

    Local area networks have been used successfully in data processing applications for several years. Recently, there have been several proposals for using these networks in real-time applications such as voice transmission. This project examines, by means of a simulation, the feasibility of using Ethernet for carrying data in real-time environments, and, in particular, studies the effect of channel ...

  • Analysis of an adaptive multiple-access protocol (ATP-1) with mixed structure

    Publication Year: 1987, Page(s):54 - 60
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (884 KB)

    In the paper a new multiple-access protocol, called ATP-1, is analysed. This protocol employs a self-adaptive scheme that switches between two states, the random-access state and the fixed-access state. The analysis is based on an embedded Markov process obtained by examining the system at the beginning of the epochs, which are defined as the intervals of random access state or fixed access state....

  • Dynamic behaviour of a new adaptive multiple-access protocol and comparison with the split-channel reservation multiple-access protocol

    Publication Year: 1987, Page(s):61 - 68
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (980 KB)

    In the paper we discuss the dynamic behaviour of a new multiple-access protocol, the ALOHA-TDMA protocol, hereafter referred to as ATP-2. This protocol belongs to the category of the self-adaptive reservation multiple-access protocols. It uses two subchannels, the request subchannel for the user's request packets and the information subchannel for their information packets, as in the split-channel... View full abstract»
