Questions tagged [diplib]

For questions on the DIPlib library and related packages, including DIPimage (MATLAB toolbox), PyDIP (Python bindings) and DIPviewer.

DIPlib is a C++ library for quantitative image analysis. Originally written in C, it has been in development at Delft University of Technology in The Netherlands since 1995. The 3.0 release of DIPlib represents a complete rewrite in modern C++ of the library infrastructure.

The DIPlib project includes interfaces to MATLAB (the DIPimage toolbox) and Python (PyDIP, a thin wrapper of the C++ API). It also includes DIPviewer, an interactive image display utility, and DIPjavaio, an interface to OME Bio-Formats, which gives DIPlib the ability to read just about any image file format.
