Error accumulate

[Ahmetcanucarli]

Hi ,
I am getting the following error while doing the Make process.
error: invalid initialization of reference of type ‘cv::InputArray {aka const cv::_InputArray&}’ from expression of type ‘std::vector::iterator {aka __gnu_cxx::__normal_iterator<float*, std::vector >}’
ave[i][j] = (0.001 + accumulate(begin(matrixi[i][j]), end(matrixi[i][j]), 0.0)) / matrixi[i][j].size();

@crankler @ShutongJIN

#include <numeric> 

and use std::accumulate to replace accumulate

[crankler]

Yes, thank you @libing64, It work

[duongtran11]

@crankler @ShutongJIN

#include <numeric> 

and use std::accumulate to replace accumulate

really helpful, thank you!

[limeiqiang]

the place is RoadMarkingExtraction/src/imageprocess.cpp and add #include in second line and use std::accumulate to replace accumulate
