AnalySIS software for image acquisition, archiving, processing, analysis and reporting offers interfaces for virtually all microscopes and cameras. It is available in three expansion levels: docu, auto and pro. Docu has its focus on image acquisition, archiving, documentation, interactive measurements and macro programming. In addition to the functions available in the docu version, auto provides a wealth of image-processing functions such as automatic analysis, morphological operators and the programming language Imaging C. Pro is the most powerful level of analySIS. Its sheer number of available functions and the embedded programming environment set up a framework that offers the latest developments in the field of digital image analysis.
