System and Evaluation

There are two approaches to texture analysis: statistical analysis and structural analysis. The difference is the level of description of textures. Statistical texture analysis gives simple scalar measurements of textures. Structural texture analysis, on the other hand, gives detailed structural descriptions of textures. Which level of analysis should be used? Comparatively, statistical analysis is suitable for fine microtextures and structural analysis for coarse macrotextures. Either approach alone cannot deal with all kinds of textures properly. In the first section of this chapter, adaptive texture analysis is presented as a total system for texture analysis, which uses either or both of statistical and structural analyses depending on nature of texture, to analyze variety of textures.
