The quantisation and entropy coding algorithms, used for the wavelet compression of 2-D and 3-D SIMS images, were adapted from the Wavelet Image Compression Construction Kit written by Geoff Davis. Some of the filtering algorithms were implemented in C and C ++ as stand-alone programs. MIE and X-image, which were developed by the authors.

Some of the figures in this chapter were generated by two image processing programs, e.g. A library of functions for calculation of scatter diagrams and statistical measures was written by the authors. The SOM package, originally written by Teuvo Kohonen and co-workers, was ported to Windows by the authors and used to classify some of the images.

In addition, the Wavelet Workbench toolbox for IDL, which is actually WaveLab ported to IDL, and the Wavelet Fusion Toolbox for IDL, were used to do some of the calculations on SGI computers. Several wavelet toolboxes for MATLAB were also used, including WaveLab and WaveBox. the Statistics Toolbox, the Image Processing Toolbox, and the Fuzzy Logic Toolbox, were used to obtain some of the results in this chapter.

A number of standard MATLAB toolboxes, e.g. Hutter, in Data Handling in Science and Technology, 2000 10 Computation and waveletsĪll computations were performed on Pentium II PCs, running Windows 95/98/NT, or on a Silicon Graphics (SGI) Power Challenge L computer and an SGI O2 computer, running IRIX 6.2. Later versions used multicast so could be used on larger networks. The initial version worked over the Ethernet using the TCP/IP protocol suite, but it didn’t actually work over a router and thus didn’t support internetworking. This version was an early demonstrator of the use of the User Datagram Protocol (UDP) (see Section 2.2), but because it sent information at the graphics frame rate, it caused a lot of network traffic. Dog should perhaps be listed under the network games section, but no doubt it inspired many serious simulators as well as NGs. The version called dog appeared in 1985 and introduced combat. XNS was an important precursor to the now ubiquitous TCP/IP.

From 1984, networking was added, first using serial cables, then using a suite of networking protocols called Xerox Network Services (XNS) which ran on Xerox’s Ethernet. Flight was a standard demonstration on the system for many years. 8 Silicon Graphics were pioneers in the development of graphics workstations, and simulators were an obvious target market.

This should only affect remote access.ĭetails are available (Cambridge Access Only) The computers have now moved behind a firewall.

And this information is for historical interest only Silicon Graphics Teaching Laboratory Access to the SGI computers will cease at the end of June 2004, when they are replaced by Linux computers New Linux Computers: Chemical Information Laboratory
