12.4.1.5 Texture Analysis
A texture is an iterative pattern put in order, for example, a pattern of a piece of
cloth is a texture. Texture analysis is performed as follows.
(1) Texture is recognized by means of texture analysis, which detects an or-
dered image pattern or chooses a different domain from a pattern. For in-
stance, a desert or a house is differentiated from a field via texture analysis.
(2) When a difference among textures is detected, a border between the two
domains is chosen.
(3) A texture is mapped on an image, and image reproduction is performed.
12.4.1.6 Detection of Texture
As shown in Figure 12.13, an area can be subdivided into smaller areas. This is
accomplished as follows. A mean value and a dispersion value of the gray level
of a small area are calculated. Given a mean value M, and a dispersion value of V/
