"Computational method" or "computation method"?

I proposed a method for computing the entropy of an image. In this case, can I refer to the method as a "computational method" or "computation method"?

What is the difference between "computational method" and "computation method"?

Thank you very much!

Solution 1:

In the first case

computational method

describes the method, that you are working out the results by computation. Another method of obtaining the results could be

empirical method

which means that it is based on observations. In the second case

computation method

describes the computation itself, given the first case. That method could be, say statistical analysis.
