he natural world is rich in texture: the surface of any visible object is textured at certain scale. A wealth of textures are observed on both artificial and natural objects such as those on wood, plants, materials and skin. In a general sense, the word texture refers to surface characteristics and appearance of an object given by the size, shape, density, arrangement, proportion of its elementary parts [99]. A texture is usually described as smooth or rough, soft or hard, coarse of fine, matt or glossy, and etc.
Textures might be divided into two categories, namely, tactile and visual textures. Tactile textures refer to the immediate tangible feel of a surface. Visual textures refer to the visual impression that textures produce to human observer, which are related to local spatial variations of simple stimuli like colour, orientation and intensity in an image. This thesis focuses only on visual textures, so the term `texture' thereafter is exclusively referred to `visual texture' unless mentioned otherwise.
Textures are usually given by examples in digitised images. Figures 4.1 and 4.2 show a few natural and man-made textures, respectively, which could be met in daily life.
Answer:
Texture refers to the physical makeup of rock—namely, the size, shape, and arrangement (packing and orientation) of the discrete grains or particles of a sedimentary rock. Two main natural textural groupings exist for sedimentary rocks: clastic (or fragmental) and nonclastic (essentially crystalline).
