In the question below I'm a bit confused about the answer.
I'm just wondering about the way to think about the answer, given that the "The discrete Fourier transform can be used" is marked as correct. To me it seems that using the DFT on an image does not remove high frequencies in itself, but truncating the frequency domain will. According to the slide below.
The question is now, when seeing a question like this, where the answer is part of a solution, will it always be considered correct, even though it is not the entire answer to the problem. Or am I completely lost?
