Error in keypoints size and descriptor rows in surf about find-object

[GoogleCodeExporter]

Hello cklwayne,

Thank you for your comment, but I am not able to reproduce the problem on my 
system (Mac OS X 10.7 Lion / Ubuntu 10.10 maverick / Windows 7 (all 64 
bits))... so I need more information.
1) Are you using the binaries (which version)? or svn (which revision "svn 
info")?
2) On which operating system are you testing? and is 32 or 64 bits?
3) Is another detector/descriptor type work ? Are you using both detector 
"surf" and descriptor "surf"?
4) Can you see images from the camera?
5) Can you copy/paste the settings found in the ".find_object/find_object.ini" 
file to this issue. (See the "Uninstall" section on the project's main page to 
know where is this file, it is in your Documents on Windows or your Home on 
Mac/Linux).

Here some information about your errors. The error "printf("ERROR : kpt=%lu != 
descriptors=%d\n", keypoints.size(), descriptors.rows);" is shown only when the 
resulting keypoints vector and the descriptors matrix rows have not the same 
size, which is never supposed to happen unless there is a problem with the 
OpenCV extractor implementations (extractor->compute(...)). 
a- If you are using the binaries, it may be a problem with the OpenCV's dlls 
provided (so I need the information above to test it). For example, it may be a 
problem between 32 and 64 bits.
b- If your are using the code from source (svn), make sure your OpenCV 
installed version is >= 2.3.1 (which is the OpenCV version I am testing with). 

If you don't have the latest version 0.2.0 or revision -r58, you could also try 
to download/update to latest version.

Best,
Mathieu

Fixed a crash in Windows (r67) with lines after the code sniplet shown in this 
issue. This fix is in version 0.2.1. Let me know if this issue persists.

Cleanup : assuming it is fixed by r67. Feel free to reopen if this problem is 
still here, providing informations of Comment 1.
