Other useful matlab tools:

Other software packages

  • OpenCV - open source computer vision. Great in combination with python. 
  • IceTools - a set of ENVI/IDL tools for post processing feature tracking output. Ice Tools can be used with  ImGRAFT output. This page explains how to export the ImGRAFT results in  a form that IceTools like.
  • PRACTISE - matlab package for georectification.
  • CIAS -  IDL gui for feature tracking. 
  • IMCORR and COSI-Corr image correlation feature trackers. 
  • Landsat-Util- an Open source command line Landsat image search, download and process tool
