I wonder what's the definition of total frequency?

Sumi Merlin

High and smooth variations b/w the adjacent pixels are called as a frequency

Marion Jaud

You may find some ideas in the section "Image Processing Toolbox" of Matlab documentation.

Are you referring to the Total Variation(TV) energy of the image ?

Oh s. But i dnt know how can i calculate?..

Peter U. Eze

I think we can talk about total energy or frequency variation ie change in pixel intensity. I don't know if FFT can help here but I need a more direct answer too.
