From: Assessing robustness of radiomic features by image perturbation
Workflow to determine the test-retest and perturbation intraclass correlation coefficients (ICC) for each feature. The test-retest ICC was calculated directly between the same features in both images. To derive the perturbation ICC, an ICC was first calculated between feature values in perturbations of image 1 (ICC 1) and then again in perturbations of image 2 (ICC 2). The perturbation ICC is the average of ICC 1 and 2.
