Need clear instructions on how to build opencvsharp with cuda to use gpu acceleration?,about shimat/opencvsharp

Hi @aloksharma1 sorry for late response, for my case after all the compilations i just took advantage of the performance gain obtained by changing the target from CPU to GPU(for example on the Computer Vision model).

thanks after @shimat said he disabled gpu support, i switched back to original compiled opencv with cuda support on python and used zero mq for cross process communication.

from opencvsharp.

Here is my opencv build cmake logs and i was able to make a build from it, but whats next?

guys, i have built the opencvextern.dll but now i am getting error on trying to compile opencvsharp with x64 release config:

total 565 error of this type, where do i need to reference the OpenCvSharpExtern release files? i tried putting them in opencvsharp solution folder and a x64 folder with this config in csproj folder:

<ItemGroup>
	<None Update="x64\OpenCvSharpExtern.dll">
		<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
		<TargetPath>runtimes\win-x64\native\OpenCvSharpExtern.dll</TargetPath>
	</None>
	<None Update="x64\OpenCvSharpExtern.exp">
		<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
		<TargetPath>runtimes\win-x64\native\OpenCvSharpExtern.exp</TargetPath>

		<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
		<TargetPath>runtimes\win-x64\native\OpenCvSharpExtern.pdb</TargetPath>
	</None>
</ItemGroup>

still the issue remains the same.

here is the dependency walker result, if that helps?

toita86 commented on June 19, 2024

Hi @aloksharma1,

I want to start by saying that I don't have the same level of knowledge as @AvenSun, as I'm still new to this stuff, but I'll do my best to help.

Let's begin with some basic checks. Just to be sure, is the NuGet package for OpenCvSharp (not the runtime) installed in your project? (Sorry if this seems like a basic question.)

from opencvsharp.

shimat commented on June 19, 2024

Are you trying to use the old OpenCvSharp implementation of GpuMat.cs, Stream.cs, etc? I think the OpenCvSharp implementation has changed so much that it is not compatible. I can't write up the solution to that here. This is probably not a problem on the C++ side, but on the C# implementation.

1>F:\CMakes\4.9\ShimatOpenCVSharp\opencvsharp\src\OpenCvSharp\Modules\cuda\GpuMat.cs(7,19,7,23): error CS0234: > > The type or namespace name 'Util' does not exist in the namespace 'OpenCvSharp' (are you missing an assembly reference?)

As for the error message about the Util namespace not being found, there is currently an implementation at

aloksharma1 commented on June 19, 2024

Hi Guys,
First of All Thank you for your reply. I am not trying to use GpuMat implementation per say , just that my mat and operations are using cuda processors thats important even if syntax is changed i am ok with it.I'm just trying to build a cuda compatible version so I can leverage my gpu, the cpu process is super slow.
@toita86 no, i am trying to build opencvsharp from source after successful compilation of opencv files & opencvexternextern folder. If i can use it without the compilation of opencvsharp project itself, please guide.

@shimat i will try your solution and will let you know before eod. i simply want gpu accelaration tow owkr with project.

Also one more question for you, my build log says:

-- FFMPEG: Downloading opencv_videoio_ffmpeg.dll from https://raw.githubusercontent.com/opencv/opencv_3rdparty/fbac408a47977ee4265f39e7659d33f1dfef5216/ffmpeg/opencv_videoio_ffmpeg.dll
-- FFMPEG: Downloading opencv_videoio_ffmpeg_64.dll from https://raw.githubusercontent.com/opencv/opencv_3rdparty/fbac408a47977ee4265f39e7659d33f1dfef5216/ffmpeg/opencv_videoio_ffmpeg_64.dll

so its downloading ffmpeg, is cmake making the cuda version of this dll? my thinking is since we have enabled cuda flags it should be doing that internally?

thanks

from opencvsharp.

shimat commented on June 19, 2024

This is my guess, but there is only one opencv_videoio_ffmpeg(_64).dll available in the repository. The CUDA flag of the OpenCV cmake has no effect on the ffmpeg DLL selection.

aloksharma1 commented on June 19, 2024

Hello @shimat i tried your suggestion and the util folder is already present in in the code. please check the screenshot here

as for the gpu mat error, i dont understand it much i downloaded and followed instructions given by you in here https://github.com/shimat/opencv_files

from opencvsharp.

shimat commented on June 19, 2024

The remaining Cuda code in OpenCvSharp has not been maintained for a long time, and unless you know a lot both C# and C++, it will be difficult to solve the problem in the short term. I discontinued OpenCvSharp's CUDA support because I was tired of dealing with issues like the one here.

This is my last reply, but perhaps the errors in your screenshot could be solved by changing namespace from OpenCvSharp to OpenCvSharp.Internal.

In addition, the corresponding functions on the C++ side must be included in the compilation beforehand. Currently they are excluded by macros.

toita86 commented on June 19, 2024

Hi @aloksharma1 sorry for late response, for my case after all the compilations i just took advantage of the performance gain obtained by changing the target from CPU to GPU(for example on the Computer Vision model).

from opencvsharp.

Need clear instructions on how to build opencvsharp with cuda to use gpu acceleration? about opencvsharp HOT 11 OPEN
