WebCreate a Gray-Level Co-Occurrence Matrix When you create a single GLCM, the default spatial relationship is defined as two horizontally adjacent pixels. Specify Offset Used in GLCM Calculation You can create multiple GLCMs with different spatial relationships between pixels to obtain additional information about textural features. A co-occurrence matrix or co-occurrence distribution (also referred to as : gray-level co-occurrence matrices GLCMs) is a matrix that is defined over an image to be the distribution of co-occurring pixel values (grayscale values, or colors) at a given offset. It is used as an approach to texture analysis with various applications especially in medical image analysis.
