Properties of GLCM.
| Property | Description | Formula |
|---|---|---|
| Contrast | Intensity contrast between a pixel and its neighbor | Σ|i–j|2p(i,j) |
| Correlation | Correlation between a pixel and its neighbor (μ denotes the expected value, and σ the standard variance) | Σ [(i–μi)(j–μj)p(i,j)/(σiσj)] |
| Energy | Energy of the whole image | Σp2(i,j) |
| Homogeneity | Closeness of the distribution of GLCM to the diagonal | Σ[p(i,j)/(1+|i–j|] |
