Hi, I want to create a visual studio project with CUDA framework and openCV library (I need openCV to read an image and then I'd like to calculate an histograme image using parallel threads). Thre's a tutorial that can explain me how I can do this?

thanks to everybody!

Build opencv with cuda and after use CMAKE to create your visual studio project. this CMakeLists.txt could be used

cmake_minimum_required(VERSION 2.8)

PROJECT (testvideo)
find_package(OpenCV  REQUIRED)
file(GLOB testvideo_SRCS
    "*.h"
    "*.cpp")
ADD_EXECUTABLE (testvideo ${testvideo_SRCS})
if (OpenCV_FOUND)
    include_directories( ${OpenCV_INCLUDE_DIRS} )
    target_link_libraries( testvideo ${OpenCV_LIBS} )
else (OpenCV_FOUND)
message("PB->OPENCV = ${OpenCV_INCLUDE_DIRS}")
endif (OpenCV_FOUND)

How can I build openCV with CUDA??

sorry for my incompetence.

If you use Cmake GUI check option WITH_CUDA and may be WITH_CUBLAS too

Command line something like that -D WITH_CUDA=ON -D WITH_CUBLAS=ON

We have a problem: we build OpenCV.sln but this isn't a CUDA project, so it doesn't find CUDA libraries. It's possible to create a Visual Studio 2012 CUDA project first, and then add OpenCV libraries?

I made CMakeLists.txt with CUDA.
Please use it as a reference.

I'm sorry but is the first time that I use Cmake, CUDA with openCV and so I haven't understand the utilization of Cmake. What's the first step I've to do???

I explain the procedure using cmake-gui.

launch cmake-gui
input the path of your souce code
input the path for build(solution file is generated in this place)
push Configure button
select your compiler and architecture(win32 or x64)
push Finish button
edit the path of OpenCV_DIR
push Configure button
push Generate button

As a result, solution file is generated in the path for build.

Sorry, I misunderstood.
I made a batch file to build OpenCV(WITH_CUDA).
Please run this batch file in Visual Studio command prompt(VS2012).

Hi dandelion1124, I have the same problem so I used your procedure but after launch the .bat file my error output is: Access is denied. The system cannot find the path specified. "cmake.exe" is not recognized as an internal or external command....and...impossible to find the files: openCV.sln... Do you have any idea to solve this problem?

Thank you very much for your help :)

Do you set the location of the cmake.exe to the environment variable (PATH)?
Because, this setting is required to run the cmake on command prompt.

"cmake.exe" is not recognized as an internal or external command....and...impossible to find the files: openCV.sln...

Maybe, I think that cmake.exe was not found.
As a result, OpenCV.sln was not generated.

Your information is so interesting and useful. Thanks for posting.

Why not use the VS13? I think there is more bugs in VS12.

Previous version CUDA does not support VS2013.
From this background, my batch file specify VS2012.

But, the latest CUDA support VS2013. So, we can specify VS2013 now.
Does that answer your question?
