OTB

Image Processing

ORFEO Toolbox Library (OTB) is a high performance image processing library. It is primarily used for processing remote sensing images such as those gathered by radars, satellites and aerial photography. OTB provides tools for the future optic and radar images (tridimensional aspects, segmentation, classification, changes detection, texture analysis, pattern matching, optic/radar complementarities,).

OTB has been funded the French Space Agency (CNES) in the frame of the Methodological Part of the ORFEO Accompaniement Program and has been actively developed since 2006. It is based on the established medical image processing library ITK(v4) and is distributed as open source.

Core Features

screenshot
  • image access: optimized read/write access for most remote sensing (including Jpeg2000 imagery through OpenJPEG) image formats, meta-data access and visualization;
  • orthorectification using DEM, map reprojection and sensor model refinement
  • calibration
  • image fusion
  • filtering: blurring, denoising, enhancement...
  • feature extraction: interest points, alignments, lines...
  • object detection
  • large scale image segmentation: region growing, mean-shift, watershed, level sets...
  • classification: K-means, Markov random fields, access to machine learning algorithms from OpenCV
  • object-based image analysis
  • geospatial analysis
  • stereoscopic reconstruction from optical images
  • SAR data analysis
  • change detection.
