A cv::Mat has a member variable 'data' that contains all values in a 1d-array so you can use it as argument. But how do you use std::max_element to get the most frequently value?

Like FooBar said, the function simply points to the element with the largest value not with the most occuring value. I can confirm that the data variable is a 1D array in memory and can thus be accessed that way.

yes i know that max_element points to the largest value not with the most .. i have a vector with counters points to different values .. then i was trying to find the max counter value that will let me know most frequently value .. this the idea that i was trying to apply it .
