I am willing to calculate no of computation in the process of applying Low pass filter(AxB) on Image having dimension NxM.
Can anyone please help out?

There are many methods to do this, since convolution to Fourier analysis among others.
If you wants to do a convolution you have to run over the image I(mn) with a mask M(AB). considering that you only run over internal parts of the image you will do (N-A)(M-B)(A*B*2) operation approximately.
Fourier filtering I have to take a look better but in bigger images is much more efficient.
