Everything about Spatial frequency
Characteristic of any structure that is periodic across a position in space
In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components of the structure repeat per unit of distance. Wikipedia →
