Image Processing Software

We report on the development of a new image processing software system SPIDER (System for Processing of Image Data in Electron Microscopy and Related Fields). The need for a user-oriented software system for electron image processing has been previously recognized /1-4/. These systems have in common that they allow users with a minimum amount of computer experience to define complex operations on images.The present system runs under the PDP 11/45 RSX-11D (Digital Equipment Corp.) executive in a multi-user, multi-task environment. Image enhancement of large images (e.g., box convolution and point mapping operations) as well as structural electron microscopy (Fourier operations, 3-d reconstruction) had to be accommodated. Characteristic for the electron microscope application is the need to process series of images closely related to each other (defocus, tilting, and averaging series).In SPIDER, the images are read and transferred by magnetic tape from the microdensitometer to PDP 11 disk files.

The Web

Zoomify Image is a mature product for easily publishing large, high-resolution images on the Web. End users view these images with existing Webbrowser software as quickly as they do normal, downsampled images. A Flash-based Zoomifyer client asynchronously streams image data to the Web browser as needed, resulting in response times approaching those of desktop applications using minimal bandwidth. The author, a librarian at Cornell University and the principal architect of a small, open-source company, worked closely with Zoomify to produce a cross-platform, opensource implementation of that company’s image-processing software and discusses how to easily deploy the product into a widely used Webpublishing environment. Limitations are also discussed as are areas of improvement and alternatives.

The National Center for Electron Microscopy (NCEM) develops software for use in image processing and image interpretation as they are needed in ongoing research at the center. Some routines are esoteric and of little use to others, while some are more general and could be considered to be of interest to a large number of scientists. This represents the first announcement of the NCEM's dedication to making software developed at the center available to the general microscopy community.An unfortunate by-product of software development is the often necessary connection of the software to a hardware platform and/or another software platform. Most of the image processing carried out at the NCEM is done under Digital Micrograph running on the Macintosh, either through the built in functionality of the program or through extensions that are written at the center. Some of the functionality that we added were routines that were available under the SEMPER image processing software which was retired not because of limitations of the program, but because of the death of the hardware on which it was running.

This paper put emphasis on discuss some peculiarity of UML apply method of object-oriented design on B/S software system. And then based on the analysis of rational unified process, modeled B/S mode image processing software system with visio 2003 modeling tools; with iterative and agglomerate modeling scheme of UML, the framework of image processing software system, which set up the base of this system, and a scheme of B/S system modeling is hold and arranged.

AbstractIn this paper we present complete two-dimensional measurements of the observed brightness of the 9th November 1990Hαflare, using a PDS microdensitometer scanner and image processing software MIDAS. The resulting isophotal contour maps, were used to describe morphological-cum-temporal behaviour of the flare and also the kernels of the flare. Correlation of theHαflare with SXR and MW radiations were also studied.
