Superresolution: error with createOptFlow_DualTVL1()

Hi

For choosing optical flow with super-resolution, the following compiles fine:

Ptr<DenseOpticalFlowExt> opflow = createOptFlow_Farneback();

But the following gives error:

Ptr<DenseOpticalFlowExt> opflow = createOptFlow_DualTVL1();

The error given is:

error C2668: 'cv::superres::createOptFlow_DualTVL1' : ambiguous call to overloaded function

How can I avoid the error? Thanks.

Add superres:: prefix:

Ptr<DenseOpticalFlowExt> opflow = superres::createOptFlow_DualTVL1();

Thanks, it works! But I'm confused on why createOptFlow_DualTVL1() needs superres:: prefix in front whilst createOptFlow_Farneback() doesn't need it. Also I have the "using namespace superres;" above the main function.

There are two function createOptFlow_DualTVL1:

cv::Ptr<cv::DenseOpticalFlow> cv::createOptFlow_DualTVL1();

cv::Ptr<cv::superres::DenseOpticalFlowExt> cv::superres::createOptFlow_DualTVL1();

If you use "using namespace ..." compiler can't decide which function used.
