Hi all I confirm the segmentation fault error with SIFT algorithm in otbcli_HomologousPointsExtraction; It is very random and when it works, it gives the desired output. There is no issue with the SURF algorithm.
I tried in Ubuntu 14.04 and Scientific linux 6.4, 7.0. In SL, it is more frequent though. The same issue is mentioned here too: https://groups.google.com/forum/#!searchin/otb-users/segmentation$20fault/otb-users/4Am13IURpXU/1fCbQE6UKh8J Any update on this issue??
