A Measure of Pattern Trends on Various Types of Preprocessed Textures

Study of different patterns on a local neighborhood of a texture plays an important role in characterization, and classification of the textures. Many preprocessing steps are used in the generation of textures for a better quality. The present paper studies how the percentage of occurrence factor of a typical pattern varies after applying various local preprocessing steps. For this eight simple patterns are chosen on a 3x3 neighborhood. The simple patterns are chosen in such a way that any complex pattern can be formed by grouping one or more of these simple patterns. The pattern occurrence factor of preprocessed images are also compared with the actual texture images, where no preprocessing is applied. The experimental results on thirty brodatz textures indicate good comparison of variation of occurrence in these patterns on different methods of preprocessed steps of the texture.
