Texture analysis is a research area within the field of computer vision and image processing that focuses on the extraction of features and patterns from images that describe the texture of the surface. These features can be used for various purposes such as classification, segmentation, and recognition of different textures. Texture analysis techniques typically involve statistical measures, filters, and mathematical models to characterize and quantify texture properties such as smoothness, coarseness, and regularity. This area of research has applications in various fields including medical imaging, remote sensing, and industrial quality control.
