The values in the frequency domain are actually complex and have imaginary components. This figure on the right shows the magnitude of the frequency domain.

Here is a question that came to my mind during the lecture. I can understand, in the Frequency Domain picture, what the points on the x and y axis represent. But how should I understand the points not in the x and y axis? Is that represent the frequency in that direction? Such as Point (1,1), is that represent the frequency in the northeast direction?
