I am working on a simple example using visual studio 2015 with opencv 4.1.0. i am not able to set value for iterator from cv::Mat sample code is shown below.
>cv::Mat inputImg = cv::imread(argv[1]);
> //convert to
> float image cv::Mat flaotImg;
>inputImg.convertTo(flaotImg, CV_32FC3, 2.0 / 255.0, -1.0);
> cv::MatIterator_ it;
>try {
> // ... Contents of your main
> **it = (flaotImg.begin());** //*Problem*
>}
>catch (cv::Exception & e)
>{
> cerr << e.msg << endl; // output exception message
>}
**Error:**
> OpenCV(4.1.0) Error: Assertion failed
