Fig. 4.
Segmentation of auto-fluorescence intensity (AF) images for skin samples with small BCC (morphemic/infiltrative BCC). r: radius of disk structuring element used for the morphological processing of tissue AF image. Color code for segmented images: red = tumor regions (diagnostic provided by histopathology) (for clarity not all tumors are highlighted), white = segment containing residual tumor, green = segments with AF intensity above threshold, gray = segment without tumor. Nseg = the number of segments.
