Figure 20: (**a**) The normalized values of the adopted measures (method I, II and III) calculated in domain of image line length \(d_{\Delta}\) for the accuracy \(\Delta=0.00001\) (for the original image shown in Figure 7b) and images reconstructed on the basis of the recorded revealing emission signals at frequency \(f_{o}=1334\) MHz (receiving bandwidth \(BW=50\) MHz, accuracy \(\Delta=0.00001\)), (**b**) for estimated line length \(d_{\Delta}=1953.64857\) and (**c**) for estimated line length \(d_{\Delta}=1953.64858\) —multiple of image summation \(Sum_{MTL}=30\), the source of revealing signal emission—display monitor, HDMI standard. Figure 23: (**a**) The normalized values of the adopted measures (method I, II and III) calculated in domain of image line length \(d_{\Delta}\) for the accuracy \(\Delta=0.00001\) (for the original image shown in Figure 7c) and images reconstructed on the basis of the recorded revealing emission signals at frequency \(f_{o}=768\) MHz (receiving bandwidth \(BW=50\) MHz, accuracy \(\Delta=0.00001\)), (**b**) for estimated line length \(d_{\Delta}=3907.26025\) —multiple of image summation \(Sum_{MTL}=60\), the source of revealing signal emission—display monitor, HDMI standard. Figure 22: The normalized values of the adopted measures (method I, II and III) calculated in domain of image line length \(d_{\Delta}\) for the accuracy (**a**) \(\Delta=0.1\), (**b**) \(\Delta=0.01\), (**c**) \(\Delta=0.001\) and (**d**) \(\Delta=0.0001\) (for the original image shown in Figure 7c). Table 11 shows the estimated values of the line length \(d_{\Delta}\) of the analyzed image. These are the values for which the criteria of the adopted methods have been met, allowing us to carry out the process of estimating the image line length for the next accuracy step \(\Delta\). 2.2 The Source of the Revealing Emission Signal in the Form of a Computer Monitor Working in the VGA Standard
