Oops, the second to last statement should be apply(norm, result). Thanks for detecting this bug for me. Michael

I am getting identifier-undefined compilation errors after porting my code from OpenCV 2.4.6 to 3.1. Examples: cv::cuda::ALPHA_OVER (was cv::gpu::ALPHA_OVER), the matrix reduction cv::cuda::minMax (was cv::gpu::minMax). Both are documented under OpenCV 3.1.0-dev. I suspect the need to include additional header files, but the documentation does not specify which ones. I am currently including core.hpp and cuda_types.hpp. Suggestions will be appreciated.

2014-05-04 15:32:39 -0600 asked a question Error building opencv_highgui in OpenCV 3.0

Trying to build OpenCV 3.0 with Visual Studio 2010 I am getting the following error:

3>------ Build started: Project: opencv_highgui, Configuration: Release x64 ------

3>Build started 5/4/2014 1:14:19 PM.


3> Touching "opencv_highgui.dir\Release\opencv_highgui.unsuccessfulbuild".

3>CustomBuild: 3> Building Custom Rule C:/LOCAL/opencv/modules/highgui/CMakeLists.txt

3> CMake does not need to re-run because :\LOCAL\opencv\build\modules\highgui\CMakeFiles\generate.stamp is up-to-date.

3> Generating src/moc_window_QT.cxx

3> The system cannot find the path specified.

As a result I am getting numerous link errors about missing opencv_highgui300.lib.

My opencv-related environment variables and path entries let my successfully build 2.4.8 (albeit on another machine). Is this possibly a new 3.0 issue?

2014-01-15 16:16:11 -0600 asked a question Missing dlls on Windows 8.1

In my app, which is problem-free on Windows 7, one of my dlls fails to load on my Windows 8.1 machine. Dependency Walker point to missing dlls: API-MS-WIN-CORE-SHUTDOWN-L1-1-1.DLL and EXT-MS-WIN-NTUSER-UICONTEXT-EXT-L1-1-0.DLL. The dlls are nowhere to be found on my machine. Searching for the offending API calls, I am wondering if they are deep inside some OpenCV functions. I am using 2.4.6, is it compatible with Win 8.1? If not, is 2.4.8?
