Table 1.
IGTD reduces the local heterogeneity (LH) of image representations compared with REFINED.
| Neighborhood size (p) | LH (IGTD) | LH (REFINED) | Reduction percentage by IGTD | P-value | |
|---|---|---|---|---|---|
| CCL | 3 | 0.174 (0.023) | 0.187 (0.026) | 6.38% (7.08%) | 2.05E−107 |

In the LH and reduction percentage columns, the number before the parenthesis is the average value obtained across CCLs or drugs, and the number in the parenthesis is the standard deviation. P-value is obtained via two-tail pairwise t-test comparing the LH between IGTD images and REFINED images across CCLs or drugs.
