Texture Analysis

Independent AI Project

"The term texture generally refers to a repetition of basic texture elements called texels. The texel contains several pixels, whose placement could be periodic, quasi-periodic or random. Natural textures are generally random, whereas artificial textures are often deterministic or periodic. Texture may be coarse, fine, smooth, granulated, rippled, regular, irregular, or linear." (A. K. Jain: Fundamentals of Image Processing)
