Question

The image of an urban area has __________________spatial frequency.
(a.) Low
(b.) Constant
(c.) High
(d.) Linear

Answer 1

it will be low I think so

Answer 2

The image of an urban area has a high spatial frequency.

Answer: option(c)

Explanation:

The spatial coverage area of this place is more when compared to others. The "spatial frequency is a measure" of how the "sinusoidal components" of the structure repeat per "unit distance".

The SI unit of spatial frequency is cycles per meter. Hence the cycle is more in the case of the urban areas. The sinusoidal component is determined by the Fourier transform.
