Figure 30: (**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 \(\Delta=1.0\) (for the original image shown in Figure 7e) and images reconstructed on the basis of the recorded revealing emission signals at frequency \(f_{o}=450\) MHz (receiving bandwidth \(BW=50\) MHz, accuracy \(\Delta=1.0\)), (**b**) for estimated line length \(d_{\Delta}=3303.00000\), image summation multiple \(Sum_{MTL}=1\) and (**c**) for estimated line length \(d_{\Delta}=3300.00000\), multiple of image summation \(Sum_{MTL}=15\) —the source of revealing signal emission—display monitor, VGA standard. Table 19 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 \(\Delta\). 2.3 The Source of the Revealing Emission Signal in the Form of Display of Laser Printer Figure 7f as a Primary Image, Display Mode Unknown, Pre-Estimated Value \(D_{Ent}=1857.00000\)
