It's main goal is to provide an environment to develop own image processing/computer vision modules. Therefore XLIPS does not (yet) provide the full range of image processing functions (may be it will one day in the future). However, it was designed to be very easy expanded. Many of the tools that are useful during development of new algorithms and computer vision methods have been implemented. It consists of 3 parts: 1) a library of I/O- and toolbox-functions which implement a object driven data model for various image types and data formats. Automatic conversion will take place (if reasonable) so that any program should be able to read/write any image type/data type (with some exceptions which are not yet implemented). In addition several "foreign" image formats are implemented such as SunRaster, TIFF, MacPaint etc. All programs can directly interact with the display module (write & read images from) by the mean of shared memory (on local machine) or by TCP/IP. 2) a display module which does allow easy interactive handling of images of any size (zoom & pan, contrast manipulation, comparing of to images by flickering in one window, display of histogram, profiling, image composing, annotation etc.). The display module requires the OSF/Motif toolkit The XLIPS display module does run up to now only on workstations with an 8-Bitplane framebuffer or accelerator. It does not yet run on 24-Bitplane Truecolor workstations (This will hopefully change in the future). However the display module simulates some Overlay functionality which can save a lot of programming effort if e.g. the result of edge detection can be displayed ontop of a grey valued image (using very simple calls - You don't have to learn all this dreadful X11-stuff !!!). In addition 2 display modules on different machines connected by a TCP/Ip network can be synchronized so that both parties will share one image window and the cursor position of the partner will be displayed. 3) A set of common image processing functions such as sobel, generic convolution, FFT, deconvolution etc. Where to find: ============= There is an anonymous ftp server wopr.chemie.unibas.ch (131.152.102.8) The source code is in the file "exlips.tar.Z", the binaries for DEC Ultrix/RISC 4.2A can be found in "exlips-bin-dec-mips.tar.Z". Documentation ------------- An introduction to the display module, library and a description of the library functions can be found in the LaTeX-file "XlipsManual.tex" or in the file "XlipsManual.ps". The directory "doc" also contains man-pages for all image processing applications. There are some undocumented features concerning networking. However these things still are very experimental. You can use it, but on your own risc... The directory "pic" contains some sample images.
