This example shows how to detect regions of texture in an image using the texture filter functions
By default, the
graycomatrix function creates
a single GLCM, with the spatial relationship, or offset, defined as two horizontally adjacent pixels.
This example shows how to create a set of GLCMs and derive statistics from them.
Texture analysis refers to the characterization of regions in an image by their texture content.
A statistical method of examining texture that considers the spatial relationship of pixels is the gray-level co-occurrence matrix (GLCM), also known as the gray-level spatial dependence matrix.
To create a GLCM, use the
