Description

I am trying to get the projection of rows and columns (i.e. sum) using cv::reduce. But it seems that it is complaining about the types of the source and destination matrices which are obviously correct in the code I have written. This seems like a bug that needs fixing. For convenience of debugging, I attached my main.cpp file to give a better picture of what I mean.

probably, the error checking has been fixed, so you get the error message. The contained sample contains a bug. The reduce call should be change to:

reduce(matImg,rowSum,0,CV_REDUCE_SUM,CV_32S);

then it works. Also, note that the allocation of the output array rowSum is unnecessary, it will be allocated automatically by the function.
