Fig. 3From: Generation of synthetic ground glass nodules using generative adversarial networks (GANs)Examples of synthetic ground glass nodules (GGNs), the GGNs were categorised by physicians to four categories: confidently fake, leaning fake, leaning real, and confidently real. a Synthetic GGNs classified as “real” by clinicians. b Synthetic GGNs with less convincing generated lesions (classified as “leaning fake”). c A real GGNs in the original LIDC-IDRI datasetBack to article page
