I have a problem with adding rows to Mat. I use push_back method but I get error: Sizes of input arguments do not match. Of course my Mats have same column length as it is said in method description.
Mat test = new Mat(new Size(10,100),5);
Mat row = new Mat(new Size(1,100),5);
test.push_back(row);
^It will result in error which I described above. Do you have any ideas how insert a row to a matrix?
According to OpenCV Java API Documentation the constructor Mat(Size size, int type) creates Mat in cols X rows order like,
Mat(Size(cols, rows), int type)
So your code should be changed to
Mat test = new Mat(new Size(10,100),5); //create mat with 10 column and 100 rows
Mat row = new Mat(new Size(10,1),5); // create mat with 10 column and 1 rows
test.push_back(row);
or
Mat test = new Mat(new Size(100,10),5); //create mat with 100 column and 10 rows
Mat row = new Mat(new Size(100,1),5); // create mat with 100 column and 1 rows
test.push_back(row);
