2019-06-17 18:32:11 -0600 | marked best answer | widthStep in C++ API Hi I had some legacy code in OpenCV C API that I want to port to C++. In the code I have some wavelet coefficients computed into a vector: I there store the vector Specifically it is a for loop that looks like this: Naively I thought I could simply replace this to cv::Mat for C++ API like this: And instead of: I would do: But this doesnt seem to work, output is all scrambled, there are some particulars of how widthStep works that I seem to miss. Helpful for any input. |
