Older releases

Throughout time support for older versions of MATLAB has been dropped. Older releases of DIPimage might support these older versions. These can be found in their respective directories on our FTP site: https://qiftp.tudelft.nl/diplib/.

Also other older platforms have been supported in previous releases of DIPlib and DIPimage. These can be found here: https://qiftp.tudelft.nl/diplib/unsupported.


The Computational Imaging Group of the TU Delft, to be called CI, has developed and is the owner of the image processing library written in C and all related documentation known as DIPlib, hereafter called SOFTWARE.

CI also developed a MATLAB toolbox for image processing based on DIPlib, known as DIPimage. DIPimage is freely available for DIPlib license holders and available for the following platforms:

as well as for some unsupported platforms, mostly for older versions of DIPimage:

1. Licenses

1.1. Source code licenses of the SOFTWARE are not available.

1.2. Non-commercial license:

1.3. Commercial licenses:

1.4. The commercial licenses for a non-supported computer platform may be provided on request. There will be minimum surcharge of 500 Euro.

1.5. All prices listed are exclusive BTW (value added tax). BTW in the The Netherlands is 21%.

2. Upgrades and Support
