Feature | Equation |
|---|---|
asm | \(asm = \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} (G(i,j))^{2}\) |
ent | \(ent = - \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} G(i,j)\log G(i,j)\) |
cor | \(cor = \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} \frac{{(ij)G(i,j) - u_{i} u_{j} }}{{s_{i} s_{j} }}\) |
dis | \({\text{dis}} = \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} G(i,j)|i - j|\) |
con | \(con = \sum \limits_{{{\text{n}} = 0}}^{k - 1} n^{2} \left\{ { \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} G(i,j)} \right\},|i - j| = n\) |
hom | \(hom = \sum \limits_{i = 1}^{k} \sum \limits_{j = 1}^{k} \frac{G(i,j)}{{1 + (i - j)^{2} }}\) |
