I've successfully compiled OpenCV 3.0 with CUDA 7 with Visual Studio 2013 makeing the solution with CMake for x64 architecture. I've notice that my *300.dll performances are slower than the already compiled *249.dll for x86 architecture (downloaded from opencv.org). For example the same sobel test program run with 2.4.9 at 30msec while run with 3.0 at 280msec O_O. How could it be possible? Have I missing some optimization or building options?

Thats my Flag for Release: //Flags used by the compiler during release builds. CMAKE_C_FLAGS_RELEASE:STRING=/MD /O2 /Ob2 /D NDEBUG

Here's my CMAKE Output

I suggest you provide your complete CMAKE output ... probably you forgot to enable a flag somewhere?

I've posted my CMAKE output. Hope it helps us to find the reason...

So you compared the performance between the pre-built *249.dll with your own build of *300.dll.

What happen if you compare the performance with the pre-built OpenCV 3.0.0 ?

Eduardo I've tried also with the precompiled *world300.dll and I've got the same lower performances than version 2.4.9. But now the question is... why with OpenCV 3.0.0 the sobel performance are so degraded than OpenCV 2.4.9?

shadowsheep ( 2015-07-30 05:18:11 -0600 )edit

Are you sure you used the same code, with the same Visual Studio configuration (release mode, compiler flags, etc.), running the executable in Visual Studio or outside ?

Eduardo ( 2015-07-30 05:27:23 -0600 )edit

Yes, the code below

int scale = 1;
int delta = 0;
int ddepth = CV_16S;

Mat grad;

int a, b;

cout << "\n STD SOBEL STARTED \n";
a = getTickCount();
Sobel(image, grad, ddepth, 1, 1, 5, scale, delta, BORDER_DEFAULT);
b = getTickCount();

printf("\n STD SOBEL FINISHED in %f, total = %f \n", 1000 * (((double)(b - a)) / getTickFrequency()), 1000 * (((double)(B - A)) / getTickFrequency()));

Run faster with OpenCV 2.4.9 than OpenCV 3.0
