I am trying to test out surf_matcher.cpp (https://github.com/Itseez/opencv_cont...), the problem is I kept getting an exception in this line perspectiveTransform( obj_corners, scene_corners, H);. The images I provided is from the hand picture at the bottom of this page (http://docs.opencv.org/doc/tutorials/...) since I can't find the box.png image for this program. I would like to know how to fix this exception and if there is another simpler version of SURF or SIFT for OpenCV 3.0.0. I am not sure what is causing the exception, maybe the image width and height, or missing libraries. If someone can give me a lead would be cool. image description

Here are the box and box_in_scene images, in case you want to try them:

I changed the two images but perspectivetransform is still giving me an exception. All I did with the code is to load it in manually since I am running it in Visual Studio imread("Test1.png", IMREAD_GRAYSCALE).copyTo(img1); imread("Test2.png", IMREAD_GRAYSCALE).copyTo(img2);. I'll update the values for the perspectivetransform.

You should post the exact exception you're getting. Otherwise is nearly impossible to know what's happening

Hi, exception images added.

Alright, it is working now that I switch to matcher_simple.cpp. Thanks for all the help!
