Node OpenCV operations on arrays

I am developing an application with NodeJS and OpenCV. I am using the node-opencv bindings done by Peter Braden (github.com/peterbraden/node-opencv)

The problem is I need to use the math array operations that OpenCV has in my NodeJS app. I mean, this, http://docs.opencv.org/2.4/modules/core/doc/operations_on_arrays.html

The idea is to implement these algorithms in Node to do normalization normalization in images https://github.com/bytefish/opencv/blob/master/misc/tan_triggs.cpp

I cannot find a way to access the functions pow, mean, substract, etc. from the OpenCV library. The native JS Math object is not suitable for this purpose as I need to do all the operations in the OpenCV matrix.

Does anyone know where the bindings to these functions are in node-opencv?

Thank you in advance
