From: Highlighting peritumoral areas in human skin cancer biopsies by infrared micro-spectroscopy
Upgraded Fuzzy C-means (FCM) images on the Fourier transform mid-infrared (FT–IR) data set of the human skin squamous cell carcinoma (SCC) sample and the corresponding hematoxylin and eosin (H&E)-stained section. Assignment of the clusters: 1 (tumor); 2 (invasive front); 3, 4 and 5 (dermis); 6 (epidermis). The color bar represents the membership value for each pixel. In the corresponding H&E-stained section, SCC is outlined.
