This paper presents two experiences in the field of high-performance SAR processing. Getting high quality SAR images in reasonably short times is getting more and more strategic for remote sensing applications, still requiring the use of data-parallel processing. Fast formation of images from radar data requires dedicated machines suited to fine-grained, DSP-based parallelism, while improving the...
The paper presents the experience of porting and using the PVM messagepassing environment on EMMA2E, an industrial, shared-memory multiprocessor architecture. The work is still ongoing in the framework of the ESPRIT “EUROPORT” project, aiming to demonstrate practical availability of portable parallel applications with related industrial and commercial benefits. The project framework, the EMMA2E architecture...
Anneal provides a means by which users can obtain significant image enhancement over other general purpose techniques for SAR noise despeckling. Its principle disadvantage lies in its rather steep computation requirements, particularly on standard sized images (2048 by 2048 and 4096 by 4096). However, PULSAR has been able to produce a portable parallel version of Anneal that has excellent parallel...
Abstract. In this paper a system for analysis and automatic indexing of imaged documents for high-volume applications is described. This system, named STRETCH (STorage and RETrieval by Content of imaged documents), is based on an Archiving and Retrieval Engine, which overcomes the bottleneck of document profiling bypassing some limitations of existing pre-defined indexing schemes. The engine exploits...
