comment How to draw Optical flow images from ocl::PyrLKOpticalFlow::dense()
Hi. Could you please explain in more detail the input arguments (e.g. use_value or sat)?

comment OpenCV: Passing a matrix as an optional argument
Thanks. As I've explained above, instead of defining the function before the main function, I defined it AFTER the main, and then declared it in the header. That caused the error. But I have no idea why.

Micka: since @B... posted his answer 2 hours earlier, I think the credits should go to him first. But I appreciate your answer. Thanks again. +1.

comment OpenCV: Passing a matrix as an optional argument
Thanks. The third solution works if I define function() BEFORE main(). Otherwise it does not work (i.e. if it is declared before, but defined after, the function main()). But I don't understand why.

comment OpenCV: Passing a matrix as an optional argument
Thanks. I figured it out. I declare that function before the main function, and define it after (see the code below), so it does not work. But I don't understand why it does not work :\ #include... Mat function(Mat matrix = Mat::eye(2,3, CV_32F)); int main() {...} Mat function(Mat matrix = Mat::eye(2,3, CV_32F)) {...}

comment OpenCV: Passing a matrix as an optional argument
Unfortunately not. I got the following error: error: default argument given for parameter 3 of ‘cv::Mat tMatch_lk(const cv::Mat&, const cv::Mat&, cv::Mat)’. I'm on 64 bits Ubuntu 14.04.

For the first two, is it possible to modify matrix and then return it? I tried the third but get the following error: error: default argument given for parameter 3 of ‘cv::Mat tMatch_lk(const cv::Mat&, const cv::Mat&, cv::Mat)’ I'm on 64 bits Ubuntu 14.04.

No I do not. I just want to pass the matrix in argument, modify it, and then return it.

Moreover, "Computer Vision and Image Processing" would attract more people. I can see that this site is dying :( P/s: I'm not the one who downvoted your answer :P

comment "Computer Vision" vs "Computer Vision and Image Processing"?
In theory, image processing is just multi-dimensional signal processing. However, in reality, most people doing signal processing are not really concerned about image processing. On the contrary, image processing and computer vision are so closely related. Take a look at the programs of any major conferences on Computer Vision or Image Processing, I think it would be clear.

Same here. Did you find any solution, JoeyPhillips?
