Hey, I am trying to use find_object_2d with RTABMAP and it works fine, except that I cannot use the SURF or SIFT algorithms under the feature2D tab in the Find-Object UI. I built OpenCV from source, and cloned the opencv_contrib module folder. Why are SURF and SIFT not showing up and how could i get them to show up? Thanks.
also, when i run sudo apt-cache search opencv, one of the lines printed are:
libopencv-nonfree2.4 - computer vision contrib library
libopencv-nonfree-dev - development files for libopencv-nonfree
Which means I also have the nonfree module. Why is find_object_2d not syncing with any of these so that I can use SURF/SIFT? Thanks.
Best,
Gabriel
