3 Open Source projects illustrate the state of Open Art and probably most of art in this field:
- Orfeo Toolbox - This project developed with blessings from CNES for processing the data from Cosmo-Skymed and Pleiades constellation. It pulls together ITK from the Medical Image processing world and various remote sensing libraries such as ossim and gdal to provide comprehensive image exploitation capabilities.
- NASA Vision Workbench - Mainly a machine vision library intended for the Mars Rovers with some Cartographic functionality thrown in via the ever present gdal. The generic camera models - Pinhole(CAVHORE) and Line Scanner are implemented allowing expansion to both ground based and aerial/spacebased sensors.
- Ossim-OpenCV extension - Ossim extension for the well known Intel OpenCV Library. This is a nascent project shows some promise in bringing the myriads of tried and tested ideas from the Machine Vision field to Remote Sensing. May be soon we will have real time face recognition and location from satellite images available to everyone - not just the NSA as shown in the movies.
