Many ways to do this, but you simple one is to use the void absdiff(InputArray src1, InputArray src2, OutputArray dst) function.

Calculates the per-element absolute difference between two arrays or between an array and a scalar.

Parameters:

• src1 – first input array or a scalar.
• src2 – second input array or a scalar.
• dst – output array that has the same size and type as input arrays.
