Dear all,

We are very happy to announce that OTB version 5.2.0-rc1 is available for testing !

Of course, some new features come with this new OTB version :

• Machine learning : regression support in machine learning models and existing classification filters + two applications dedicated to regression training and prediction.

• SAR imagery : basic support of Sentinel1 products, radiometric calibration updated, new SAR processings (polarimetry, decompositions, conversion of polarimetric matrices to each other) and related new applications.

• A better no-data support : Read, Manage, Write no-data in OTB.
• A richer Python wrapping : numpy array support, new way of writing an application in Python

In addition, two new remotes modules are shipped with OTB :

• Generic Region Merging Segmentation: providing the GRM OTB application to perform multi-scale region-merging segmentation on satellite images. Three local homogeneity criteria are available: the Baatz & Schäpe criterion, the Full Lambda Schedule criterion and the simple Euclidean Distance criterion.
• Images mosaicking: one application dedicated to images mosaicking with several compositing methods available (radiometric/color harmonization, feathering).

You can obtain the OTB source code using Git:

git clone https://git@git.orfeo-toolbox.org/git/otb.git OTB
cd OTB
git checkout -q --detach 5.2.0-rc1

Please test the release candidate and share your experiences on the mailing list and Mantis to help identify issues.

You can also submit experimental build to the dashboard with:

ctest -D Experimental

Congratulations and well done to everyone that contributed to this release. (Big up to OTB-dev team wich did an amazing work)

The final release is expected by the end of next week, if no showstopper is raised.

Regards,

Rémi, release manager of OTB5.2
