Description

Hello,

I noticed a problem with cuda::integral, specificly vertical_pass.

OpenCV Error: Gpu API call (unspecified launch failure) in integral, file /var/tmp/portage/media-libs/opencv-9999/work/opencv-9999/modules/cudev/include/opencv2/cudev/grid/detail/integral.hpp, line 614
terminate called after throwing an instance of 'cv::Exception'
what(): /var/tmp/portage/media-libs/opencv-9999/work/opencv-9999/modules/cudev/include/opencv2/cudev/grid/detail/integral.hpp:614: error: (-217) unspecified launch failure in function integral

The vertical_pass call fails for certain row sizes (eg. 1066).
I prepared a program that reproduces that problem.
The cv::integral call succeeds, the cuda::integral call fails with the mentioned Error message.

#include <opencv2/cudaarithm.hpp>
#include <opencv2/imgproc.hpp>

using namespace cv;
using namespace cv::cuda;
using namespace cv::cudev;

int main(int argc, char *argv[])
{
    const Size size (768, 1066);
    Mat src (size, CV_8UC1), dst;
    cv::integral(src, dst);

    GpuMat g_src(src),g_dst;
    cuda::integral(g_src, g_dst);
    return 0;
}

I tested with Gentoo Linux, and Windows 7.
