OTB at FOSS4G!

If by any chance you attend FOSS4G in Nottingham, do not forget to see the talk about OTB meeting OpenCV! See you on friday morning at 12:00 (EMCC, room 4). And it seems that the previous talk in the session will also partly deal with OTB, so you might as well attend the whole session. I will be delighted to meet you in Nottingham!

See you there,

Julien

New version Monteverdi2 0.4 Released

We are very happy to announce the release of Monteverdi2 version 0.4!

If you only have a few seconds to read this post and want to help us making Monteverdi 2, here is a short summary:

  1. Download Monteverdi2 0.4 (Windows and Mac OS X installer available, please note that installers does not require any privilege). For Linux users, new version will be soon available for update through your favorite package manager software. As usual sources can also be downloaded here.
  2. Give it a try
  3. Fill the new Monteverdi2 0.4 survey (French version available here)
  4. (Optionally) file bugs on our our bugtracker

Regarding the novelties of Monteverdi2 0.4, there have been three major improvements:

  1. Processing through the OTB applications is available (was the top feature request)
  2. A simple database manager which allows to open multiple images in the application has been added. It was not the second top feature request, but was a necessary step toward multiple images visualization.
  3. Some more rendering options have been added : no-data handling, unconstrained mode, gray-scale mode. Their will be more to come in the future. New widgets have also been added, as well as more persistence (last roi and zoom level).

We would like to thank the 35 users that sent their feedback through the previous poll! We tried to take it into account as much as we could. You could find in the introduction of the new Monteverdi2 survey, the improvements made to Monteverdi2 to answer some of your feedback. Please note that some comments have not been answered yet and that we will try to do it in a future version.

 We wish you all a nice summer with Monteverdi2 !

OTB 3.18.1 Released

We are pleased to announce the release of OTB 3.18.1.

This is a minor bug-fix release in preparation for the upcoming version of Monteverdi2. We have especially rework the JPEG2000 driver to decrease the cache consumption and avoid memory leak.

The list of changes since 3.18.0:

* Library
  * Core and Third Parties
    * Update the JPEG2000ImageIO to decrease cache consumption and avoid memory leak between OTB and internal OpenJPEG library
    * Improve the control over the generation of GDAL overviews with a new method to set the resolution factor

  * CMake
    * remove OTBParseArguments from OTB source because it is not used

  * Examples
    * Update HelloWorld example CMakeLists

  * Applications
    * Updated applications
      * Update Stereo application documentation example with new parameters
      * Add a log message about color mapping method used by application
    * Core Framework
      * Intialize properly QtWidgetChoiceParameter
    * Increase minimun cmake version to 2.8.3 wwhen build applications

 

We recommend that all users update to 3.18.1.

Thanks again to all the contributors for the great work and to all the users for their feedbacks.

As usual, sources and binary packages (Monteverdi for Mac OS X and Windows) can be downloaded here. Binary packages (OTB applications and Monteverdi) are also integrated in OSGeo4W for Windows user.

For Linux users, new version will be also soon available for update through your favorite package manager software (it is already available on Ubuntu).

We welcome your feedback and request, and encourage you to join the community and mailing list.

Let’s move now to Monteverdi2!

Roll over Monteverdi2

All you need to know

If you only have a few seconds to read this post and want to help us making Monteverdi 2, here is a short summary:

  1. Download Monteverdi2 beta version here (Windows and Mac OSX installer available, please note that installers does not require any privilege).
  2. Give it a try
  3. Fill Monteverdi 2.0 beta1 survey (french version available here)
  4. (Optionally) file bugs on our our bugtracker

Why Monteverdi2, and how it’s done

Monteverdi was developed 4 years ago  in order to provide an integrated application for capacity building activities (teaching, simple image manipulation, etc.). Its success went far beyond this initial scope since it opened the OTB world to a wide range of users who needed a ready to use graphical tool more than a library of components to write their own processing chain. With this 4 years of lifetime, we have a lot of feedbacks regarding how useful the tool was, but also regarding what should be improved to move toward greater usability and operationnality. We therefore decided to rework the Monteverdi concept into a brand new software, enlightened by this experience.

We are now very happy to announce the first beta version of Monteverdi 2, the new generation of interactive application based on OTB. Please note that we are still at an early development stage, as this is only the first step of an iterative process we would like to conduct with you. In this process, we :

  1. Deliver a beta version,
  2. Collect your feedbacks and advices for the next beta version,
  3. Work on the next beta version taking into accounts all the feedbacks.

By actively including you (the end-user) in a short development loop, we hope to converge faster toward the tool you really need !

For now, Monteverdi 2.0 allows you to :

  • Open an image in a viewer Navigate through space and resolution using drag&zoom
  • Change color composition and rendering
  • Visualize the viewed area on a minimap
  • Close and open again your data with the exact same parameters

Capture Monteverdi 2.0

More to come

As stated before, this is only the first beta version, and we have a lot of ideas regarding what the software could do :

  • Adding an image collection manager (like a photo manager),
  • Allowing access to processing with OTB applications,
  • Adding more visualisation modes and tools …

Take the survey !

Instead of selecting ourselves the new features to implement, we would like to select the features you really need or care about. That is why we wrote a short survey to allow you to give your feedback on what is already available and what we should focus on for the next beta version. Please take the Monteverdi 2.0 beta1 user feedback Survey, it will only take about 10 minutes of your time (french version also available here).

Also, if your run into something likely to be a bug, do not hesitate to file a bug report in our bugtracker ! This is very important to improve the software quality.

Many thanks for your help,  we hope Monteverdi2 (will) rock(s) !

OTB 3.18 is out!

We are very happy to announce the release of OTB 3.18 codename “Seven years of Coding”!

Some of the major changes in this release are:

  • OTB meets OpenCV: the architecture of the machine learning framework has been redesigned. It provides a simple and generic interface to create bridges with existing machine learning algorithms implementation. This new framework has been used to include  OpenCV machine learning algorithms. So in addition to LibSVM,  you can now use 8 other algorithms  for your images classification tasks, such as bayesian, k-nearest neighbors, random forests, artificial neural network… All these classifiers can be reached directly from the TrainImagesClassifier and ImageClassifier applications (read this note to learn about migrating to these new applications).
  • Dempster-Shafer based fusion of classifications: A new method based on Dempster-Shafer theory has been developed to fuse multiple classification maps. This method will take advantage of the per-class strengh and weaknesses of each input classification (estimated from confusion matrices) to produce a robust output map combining the best of each input. It is available as an alternative choice to majority voting fusion in the FusionOfClassifications application.
  • Improvement of the StereoFramework application: a whole set of filters has been developed to enhance this application, including line-of-sight intersection, left-right / right-left coherency checking and fusion of several 3D clouds into one raster DSM. The application now allows to input several views of the same scene and build a single raster DSM from them combining the information from all pairs, which is most useful for tri-stereoscopic Pleiades data for instance.
  • Access to GDAL overviews and writing of output image subsets throughout the library using the box and resol parameters of the extended filenames.

There are also a great deal of major improvements in the core library (as listed in the release note).

Thanks again to all the contributors for the great work and to all the users for their feedbacks after the release candidate, especially Morgan and Agustin who helped spotting bugs and documentation flaws.

As usual, sources (OTB, Monteverdi, OTB-Wrapping) and binary packages (Monteverdi for Mac OS X and Windows) can be downloaded here. For Linux users, new version will be soon available for update through your favorite package manager software.

We welcome your feedback and request, and encourage you to join the ORFEO community and mailing list.

OTB is not yet “On The Beach” as we’re expecting to release a new beta version of Monteverdi2 in few days with major improvements.
