  • The Oxford parallel architecture for 3D vision

    Publication Year: 1991 , Page(s): 2/1 - 2/5
    Click to expandAbstract | PDF file iconPDF (240 KB)  

    A hybrid architecture for machine vision is described. The primary components of the architecture are a Datacube pipelined image processor, a configurable network of 32 T800 transputers, a Sun-4 workstation and a special-purpose interface connecting the Datacube to the transputer network. The implementation of a 3D structure-from-motion vision algorithm (Droid) on this architecture is described. T... View full abstract»

  • Parallel stereo matching of SPOT satellite images

    Publication Year: 1991 , Page(s): 10/1 - 10/4
    Click to expandAbstract | PDF file iconPDF (240 KB)  

    Most recently, an area based region growing stereo matcher [Otto & Chau 1989] using an adaptive least-squares correlation was developed by the Alvey MMI-137 project. This algorithm (coded in C) is being used as the second step in a completely automated system for extracting 3D co-ordinates of terrestrial and industrial surfaces from stereo images, the first step is being the extraction of some...

  • Multiprocessor techniques for use in low-cost vision systems

    Publication Year: 1991 , Page(s): 4/1 - 4/4

    Many applications of artificial-vision systems are complex and computationally expensive and so demand powerful and therefore expensive processing units. However, there is also a place for low-cost systems. Artificial vision systems for use in manufacturing industry may need high speed response, but not all manufacturing applications do. High resolution is sometimes needed, but often working with ... View full abstract»

  • Pipeline functional algorithms, data partitioning for adaptive transform coding algorithms

    Publication Year: 1991 , Page(s): 8/1 - 8/6
    Cited by:  Patents (2)

    Image compression algorithms based on block transform coding have been adopted by the CCITT for coding of visual telephony. Recent developments in block transform coding show that by incorporating adaptive blocksizes, the efficiency in terms of bit-rate and subjective image quality of such coding methods are improved. The characteristics of this Scene Adaptive Transform Coding algorithm are introd... View full abstract»

  • Generalised parallelism for embedded vision applications

    Publication Year: 1991 , Page(s): 1/1 - 1/4
    Click to expandAbstract | PDF file iconPDF (152 KB)  

    Parallel architectures have yet to achieve the generality of sequential processing, particularly in areas such as image processing and vision. The main reason why parallel processing does not exhibit the same generality as sequential processing is because a large number of new degrees of freedom have been introduced for both the compiler writer and programmer. They include class of architecture, t... View full abstract»

  • Integrated architecture for space-based and ground-based image processing

    Publication Year: 1991 , Page(s): 3/1 - 3/5
    Click to expandAbstract | PDF file iconPDF (292 KB)  

    British Aerospace (Space Systems) Ltd. is currently developing an integrated digital signal and image processing architecture for the European Space Agency. It is intended that this multiprocessor architecture will become an open system standard for demanding space-based applications. The architecture is also directly applicable to many ground-based image processing applications. This paper presen... View full abstract»

  • Techniques for motion video processing on transputer-based reconfigurable multicomputers

    Publication Year: 1991 , Page(s): 7/1 - 7/5
    Click to expandAbstract | PDF file iconPDF (184 KB)  

    The design of motion video image compression algorithms has been a very time consuming process when carried out with the aid of serial computers. Without real-time or near real-time simulation aids it is difficult and tedious to assess the performance of different algorithms. Recently the CCITT set an international standard for motion video codecs, H.261, which took several years to develop. The a... View full abstract»

    An architecture of a dynamically reconfigurable, multidimensional multidirectional parallel pipelined (M2P 2) system is presented for real time image processing applications. It is implemented as a chain of interconnected modules, each having high performance TMS320c25 processing elements (PEs). These PEs can be configured to operate as independent stages of...

  • Transputer topologies for image sequence transmission

    Publication Year: 1991 , Page(s): 9/1 - 9/5
    Click to expandAbstract | PDF file iconPDF (216 KB)  

    An image coder, based on the CCITT H261 recommendation for real-time coding and decoding of moving video images, is presented. The coded images include a minor departure from the H261 recommendation as the transmission of video conferencing images is intended for a LAN (Local Area Network) environment. This project extends the coding algorithms to include video images. A secondary objective is the... View full abstract»

    Click to expandAbstract | PDF file iconPDF (164 KB)  

    A transputer network is used for visual texture analysis. The image is segmented and farmed amongst the transputers of the network. The analysis is based on fractal texture measurements, modified to be suitable for non-fractal visual texture from natural scenes. Gravity feed dynamic load-balancing is used for data distribution, with software written in a modular fashion to facilitate changes in to... View full abstract»
