The DIPlib project contains: * DIPlib, a C++ library for quantitative image analysis. It has been in development at Delft University of Technology in The Netherlands since 1995. The 3.0 release of DIPlib represented a complete rewrite in modern C++ of the library infrastructure, with most of the image processing and analysis algorithms ported from the previous version, and some of them improved significantly. * DIPimage, a MATLAB toolbox for quantitative image analysis. It has been in development at Delft University of Technology in The Netherlands since 1999. * PyDIP, Python bindings to DIPlib. This is currently a thin wrapper that exposes the C++ functionality with little change. * DIPviewer, an interactive image display utility. It is usable from C++, Python and MATLAB programs. Within DIPimage this is an optional alternative to the default MATLAB-native interactive display utility. * DIPjavaio, an interface to OME Bio-Formats, a Java-based library that reads hundreds of image file formats. This module is usable from C++ and Python (DIPimage interfaces to Bio-Formats natively).
