c++ - Unhandled exception OpenCV -

-

i working on object tracking using surf assignment. code runs on ubuntu webcam doesn't work on need make work on windows (visual studio 2010, opencv 2.4.3) demo.

my code based on this: http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html

i'm guessing if solved, code start working.

the error is:

unhandled exception @ 0x75b92eec in sift.exe: microsoft c++ exception: std::length_error @ memory location 0x00c6e328..

any idea how solve this? think have added necessary libraries because builds successfully.
