Hey there,
I try to getting started with openCV but can't get aournd with a few things. I have an array of doubles and want to show it as an imgage with imshow. But this only accepts an InputArray mat type. How can I convert the double array to an InputArray?
For small matrices you may use comma separated initializers like
Mat A = (Mat_<double>(3,3) << 0, -1, 0, -1, 5, -1, 0, -1, 0);
Or you could use Mat constructors to initialize Mat with a data pointer like
Mat::Mat(int rows, int cols, int type, void* data, size_t step=AUTO_STEP)
or
Mat::Mat(Size size, int type, void* data, size_t step=AUTO_STEP)
See OpenCV Doc for more details.
Also see the answer here might be helpful.
