Measures the joint probability occurrence of the specified pixel pairs. spatial relationships of pixels in an image.). Most thin film textures may be categorized as one of two different types: (1) for so-called fiber textures the orientation of a certain lattice plane is preferentially parallel to the substrate plane; (2) in biaxial textures the in-plane orientation of crystallites also tend to align with respect to the sample. The function estimates corners as 3-D coordinates in world coordinate system. Sample wavelength in increasing powers of two starting from 4/sqrt(2) up to the hypotenuse length of the input image. Entropy is defined as -sum(p.*log2(p)), where p contains the normalized histogram counts returned from imhist. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. and materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric).A sample in which these orientations are fully random is said to have no distinct texture. The goal is to segment the dog from the bathroom floor.
