Hi,

Does OpenCV with IPP supports remap function(speed up remap function)?

Best regards Viktor.

Thanks. I will ask emgu support.

I am using emgu. Emgu hasn't CudaInvoke.Transpose. Now i am doing: mapx[i,j]=j; mapy[i,j]=i; CvInvoke.Remap is ok, but CudaInvoke.Remap return black image It is bug?

Hi,

I want remap image like transpose function. Anybody knows matrix or algorithm for transposing source matrix?

Best regards Viktor.

If i use FeaturesMatcher without CUDA, then no error:

Ptr<detail::featuresmatcher> featuresMatcher = makePtr<detail::bestof2nearestmatcher>(false, 0.65f); stitcher.setFeaturesMatcher(featuresMatcher);

But stitch with CUDA not faster than without CUDA in opencv 3.0 beta. Also default blender/seamfinder with CUDA not good.

Hi,

stitcher = Stitcher::createDefault(true); Mat pano; vector<mat> imgs; imgs.push_back(img1); imgs.push_back(img2);

stitcher.stitch(imgs, pano);

Last line throws error:

OpenCV Error: Assertion failed (func != 0) in knnMatchSingle, file /home/hyper/Downloads/opencv-3.0.0-beta/modules/cudafeatures2d/src/brute_force_matcher.cpp, line 503 terminate called after throwing an instance of 'cv::Exception' what(): /home/hyper/Downloads/opencv-3.0.0-beta/modules/cudafeatures2d/src/brute_force_matcher.cpp:503: error: (-215) func != 0 in function knnMatchSingle

Stitching without GPU - OK.

Any ideas?

Thank you.

Resolved.

Opencv 2.4.9 same result.

But if running under root DEVICE DETECTED

Also gcc4.8 not playing with CUDA together. I use gcc4.7

Thank you all. CLOSED.

Hi,

I want use CUDA acceleration for my opencv based project.

I have installed latest nvidia drivers, nvidia toolkit, opencv 3 beta with_cuda=on

But getCudaEnabledDeviceCount is always return 0

Please help

Nvidia deviceQuery is here: http://verti.ee/etc/deviceQuery.txt Compiler output is here: http://verti.ee/etc/make.txt
