Assessment of the algorithm sensitivity, w (1), w (2) and w (3) to the change of the number of rows and columns of the analyzed are in the range from M × N =10×10 to 90×90. The graphs show the changes in individual features in response to changes in the size of the selected ROI. The graphs indicate that the features w(1) and w(2) are very sensitive to the size of the ROI. The smaller the ROI is, the bigger the measurement error of the values w(1) and w(2) gets. The feature w(3) is less dependent on the size of the ROI.
