Spatial frequency
Spatial frequency refers to the level of detail present in an image or pattern, often described in terms of how quickly colors or intensities change over space. In simpler terms, it measures how fine or coarse the visual information is. High spatial frequency indicates rapid changes, like sharp edges or intricate details, while low spatial frequency represents smoother, more uniform areas. In fields like photography, art, and vision science, understanding spatial frequency helps explain how we perceive textures, shapes, and overall image quality. It plays a critical role in both visual perception and image processing.

Spatial frequency refers to the detail level in an image or pattern, measuring how quickly changes occur in intensity or color over space. Imagine a smooth gradient—this represents low spatial frequency because changes are gradual. In contrast, a pattern with many sharp lines or textures, like a checkerboard, has high spatial frequency due to abrupt changes. Understanding spatial frequency is key in various fields, including photography, vision science, and image processing, as it helps explain how we perceive details and textures in the world around us.
