hello,
i want to compute a feature for image processing that uses coefficients from the haar wavelet and has this form :
and the coefficients are :
i have the coefficients but i am not very good at math.Can someone help me with this?

That's fine..still unclear on what k and l are though. In the above, you are asked to compute f. Since you have two sums, you start with the first, so i equals to zero, and compute the inner sum where you just square the two coefficients and sum them together. These coefficients would be C(k,l) and C(k,l+1) for j equals to zero and j equals to one respectively. You then repeat this for i equals to one and sum the result with that which you found for i equals to zero. The remaining operations should then be clear.
