Several features can be derived from the GLCM to describe the textures in histological images. Some of the key features include: - Contrast: Measures the intensity contrast between a pixel and its neighbor over the entire image. - Correlation: Provides a measure of how correlated a pixel is to its neighbor over the entire image. - Energy: Also known as uniformity or the angular second moment, measures the sum of squared elements in the GLCM. - Homogeneity: Measures the closeness of the distribution of elements in the GLCM to the GLCM diagonal.
