Description

Hi all,
I find a bug when create mat variable.
I using mat.create(size,CV_64FC1), the rows size change cols size, and cols size change rows size.
Code list here.

@ Mat src2;
Mat src3;

half_win = (win_size) / 2;
    win_count = win_size * win_size;
dst.create(src.size(),src.type());
    src3.create(cv::Size(src.rows+2*half_win,src.cols+2*half_win),CV_64FC1);
    //src3.create(cv::Size(src.cols+2*half_win,src.rows+2*half_win),CV_64FC1);
    src2.create(cv::Size(src.rows+2*half_win,src.cols+2*half_win),CV_8UC1);@

OS: Windows 7 x64 & Opencv ver:2.4.3

Size constructor signature:
Size::Size(int width, int height)

Mat create signature:
void Mat::create(int rows, int cols, int type);
void Mat::create(Size size, int type);

Sou you should use
mat.create(rows, cols, type);
or
mat.create(Size(cols, rows), type);
