Figure 3From: Calibration and segmentation of skin areas in hyperspectral imaging for the needs of dermatology Graph of changes in average brightness values for each column of the pattern. The image a) and its zoom b) show the differences in average brightness values. The image must be calibrated with respect to these changes. These values L w (n,k) are shown for the sample k = 400, 401 and 402. For each value k, calibration must be performed independently.Back to article page
