Texture

Texture is a term that refers to properties that represent the surface of an object; it is widely used, and perhaps intuitively obvious, but has no precise definition due to its wide variability. We might define texture as something consisting of mutually related elements; therefore we are considering a group of pixels (a texture primitive or texture element) and the texture described is highly dependent on the number considered (the texture scale) [Haralick 79]. Examples are shown in Figure 13.1; dog fur, grass, river pebbles, cork, chequered textile, and knitted fabric. Many other examples can be found in [Brodatz 66].
