Orfeo Toolbox: aplicativo opensource para processamento, segmentação e classificação de imagens



Mais uma excelente opção opensource para tarefas de Sensoriamento Remoto. Vale a pena conferir.

Orfeo Toolbox

ORFEO Toolbox (OTB) is distributed as an open source library of image processing algorithms. OTB is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. OTB is distributed under a free software license CeCILL (similar to GPL) to encourage contribution from users and to promote reproducible research. The library is intensively tested on several platforms as Linux, Unix and Windows. Most functionalities are also adapted to process huge images using streaming and multi-threading as often as possible.

Among other, OTB provides a number of heavily documented functionalities as:

  • image access: optimized read/write access for most of remote sensing image formats, meta-data access, visualization;
  • filtering: blurring, denoising, enhancement;
  • feature extraction: interest points, alignments, lines;
  • image segmentation: region growing, watershed, level sets;
  • classification: K-means, SVM, Markov random fields;
  • change detection.

    Following on this recent annoucement, the necessary OrfeoToolbox
    binaries to run the modules in Qgis are available in the OSGeo4W

    It is now straightforward to get the OrfeoToolbox up and running in Qgis
    on Windows machines.
    Installation instructions [1] have been updated to reflect this.

    Thanks to the OSGeo4W team to make this possible !

    Best regards,


  2. Jorge,
    Você poderia criar um tutorial de instalação dessa ferramenta no QGIS… Ela é excelente! E pelo que soube, estará dando suporte a interpretação de imagens de RADAR (Cosmo-SkyMede) também.
    Um abraço.

    • Opa! Vou colocar essa dica na minhas lista, @sadeckgeo.
      Tutorial de integração Orfeo/QGIS na linha de produção!

      Grade abraço, Jorge Santos
