DIPlib 3

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. Read the DIPlib documentation.

• DIPimage, a MATLAB toolbox for quantitative image analysis. It has been in development at Delft University of Technology in The Netherlands since 1999. Read the DIPimage User Manual.

• PyDIP, Python bindings to DIPlib. This is currently a thin wrapper that exposes the C++ functionality with little change. Read the PyDIP User Manual.

• 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. Read the DIPviewer documentation.

• 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). Read the DIPjavaio documentation

See the DIPlib website for more information.

Building and using the project

To build the library you will need a C++14 compliant compiler and CMake. Please see INSTALL.md for detailed instructions.

When linking against the DIPlib library without using CMake, it is important to set a few preprocessor macros. Please read at the bottom of INSTALL.md for details.

Contributing

Reporting a bug

We use the issue tracker on GitHub to manage bug reports. See CONTRIBUTING.md for instructions on how to report a bug.

Bug fixes, algorithm improvements, new algorithms

Feel free to submit a pull request on GitHub. Please follow our style guide and make sure to read CONTRIBUTING.md first.

Documentation, tutorials

Documentation can always be improved (also, PyDIP has hardly any at all!). If you want to help write documentation, or create tutorials for how to use the library, read CONTRIBUTING.md, then submit a pull request on GitHub.

If you found an error in the documentation, we consider this a bug. See above how to report it.

  X-Consortium license

• GLFW (as installed on your system, alternative to FreeGLUT)
