Description

In the include file "opencv2/opencv.hpp" the nonfree header "opencv2/nonfree.hpp" is not included. (Reviewed it in revision 8317). Therefore the example on page 48 of the refmanual for the sift features causes the error: "initModule_nonfree(); is not declared in this scope".

If it is not desired to include the nonfree header in the opencv.hpp (because 'stitching is not included either') then the example has to be fixed (#include "opencv2/nonfree/nonfree.hpp")

calls for methods on Feature2D Pointer "sift" are wrong:

  • sift.read(...) should be sift->read(...)
  • sift.set(...) should be sift->set(...)
  • sift.write(...) should be sift->write(...)
  • sift(image, noArray(), keypoints, descriptors); should be (*sift)(image, noArray(), keypoints, descriptors);

Thanks for the report.
Fix is committed to the OpenCV trunk.
