Fig. 4From: Segmentation in dermatological hyperspectral images: dedicated methodsSchematic diagram of filtration for the 8-neighbourhood system: a location of a sample pixel of the matrix L V (m, n, i); b sample results, image L S (m, n) for the image of a healthy thumb. Red, green and blue indicate the results of thresholding of the image L S (m, n) with the thresholds p r1 = 30 %, p r2 = 20 % and p r3 = 10 %Back to article page
