Left: Viable tumor tissue classification, where blue represents the gold-standard segmentation, green represents the classification based on structural context features alone, and red represents the segmentation achieved by our method integrating structured and rotationally invariant context features. Right: Dice similarity coefficient (DSC) for viable tumor tissue classification for each classification iteration (“Spher. Harm” = spherical harmonic contextual feature encoding, “Shell Hist.” = histograms of contextual features on shells).
