I want to use N-SIFT (n-dimensional scale invariant feature transform)feature points to detect some spatio-temporal scale invariant regions in a video. I have got the code from the following link http://www.insight-journal.org/browse/publication/207

It builds the tool on Cygwin platform and uses ITK. No detailed description is given on how to build it. So if any one using this tool/library please help me to build it. Or please mention any other library for the same if available.

To build the project I needed to add following line to CMakeLists.txt file:

cmake_minimum_required(VERSION 3.0) # <- give version you have

and change all lines:

TARGET_LINK_LIBRARIES ( ... ITKCommon ITKIO)

into

TARGET_LINK_LIBRARIES ( .... ${ITK_LIBRARIES})

..and use CMake to build it, e.g.:

mkdir build
cd build
cmake ../
make

If you only process 2-D video, you can also use ASIFT library you can find it here: http://www.ipol.im/pub/art/2011/my-asift/

  • Thanks for replying. I am trying to build it on 64 bit windows 7. I have made the changes and configured using gui based cmake (version 3.0.1). It worked without error but how to connect with ITK tool? And how to call the library?do I need to call from the cygwin command window? Will configuring and generating using gui based cmake does the work? – Nilkanta Sahu Sep 17 '14 at 17:52
  • I don't understand what exactly "connect with ITK tool" means. You can find examples how to use n-sift filter with other ITK filters in "testnD.cxx" program in the project main directory. After build the project on Archlinux platform I successfuly run "make test" which calls "testnD.cxx". – ralv Sep 19 '14 at 04:16

For me the answer of ralv worked, but I also had to manually set the ITK-DIR variable in the cmake configurations (I used ccmake to do the configurations, instead of cmake) to the directory where the file ITKConfig.cmake was located.
