Assume that the size of the filtered 2D image is N × N, where N is very large. Write the minimum number of arithmetic operations separated by a space, from the one corresponding to the filter f₁ to the one corresponding to f4. For example, if f₁ required 1 addition and 1 multiplication per sample, ƒ2 2 additions and 2 multiplications per sample, f3 3 additions and 3 multiplications per sample, and f4 4 additions and 4 multiplications per sample, the correct answer would be:
