The Tile and General Research Imaging System (TIGRIS) 总被引:1,自引:0,他引:1
The Tile and General Research Imaging System (TIGRIS) is a UNIX-based image software system implemented in, and strictly conforming to, UNIX, C/ANSI C, and X11 Window standards. The TIGRIS design and implementation emulates UNIX at the user, application, and system levels. The TIGRIS Application Programmer Interface (API) provides a convenient way to create diverse image processing and analysis applications. TIGRIS has been used primarily to support satellite remote sensing, global change research, and operational activities. Numerous applications related to specific remote sensing issues (e.g., cloud detection, noise reduction in AVHRR Channel 3 data, oceanic transport) are included in the application layer. In addition, a number of powerful general purpose imaging applications (e.g., image algebra, morphological operations, textural analysis) are provided which support general image processing, analysis, interactive visualization, and noninteractive image product generation. Use of TIGRIS to accomplish a few complex image analysis tasks is demonstrated 相似文献

The authors present a general system design method which is intended to support parallelisation of complete image processing applications using MIMD processors. The approach is based upon the utilisation of a generic system level parallel processor architecture, the `pipeline processor farm'(PPF), and is applicable to any embedded application with continuous input/output. The design method is illustrated using applications from the fields of computer vision and image coding. The design model accommodates several commonly exploited parallel processing paradigms, maps conveniently to the software structure of most image processing algorithms, provides incrementally scalable performance, and enables upper-bound speedups to be easily estimated from profiling data generated by the original sequential implementation of the application. It is believed that the approach has significant application in parallel embedded systems design, in the development environment, and in simulation work for computationally intensive image coding algorithms 相似文献

It is argued that ISDN computer-aided telephony requires properly architected platforms to satisfy changing application needs during the 1990s. Proper architecting necessitates the use of functionally rich and consistent telephony application programming interfaces (APIs). Other APIs are also needed to support integrated applications. The coexistence of telephony and other APIs must be accommodated in the ISDN driver architecture to make efficient use of D-channel signaling and voice, data, or image communications on the associated B/H channels. This driver may support Open Systems Interconnection (OSI), Systems Network Architecture (SNA), X.25, or other protocol stacks in the same computer using a single ISDN access link. Applications being currently explored show that significant benefits can be realized using incoming call management and LAN-based image server access by means of ISDN. It is envisioned that by the year 2001, a common API will facilitate multimedia applications on multivendor platforms architected within the OSI framework. These platforms will support interconnections of public and private ISDNs and bridging to BISDNs 相似文献

Properties determining choice of mother wavelet 总被引:3,自引:0,他引:3

Properties of wavelets with finite as well as infinite support are summarised to facilitate mother wavelet selection in a chosen application. The quantitative guidelines reduce dependence on trial-and-error schemes resorted to for selection and underscore the importance of such selection in any application of interest. In wavelet-based image sequence superresolution, studied during the last four years, the use of a B-spline mother wavelet is justified. 相似文献
