## 6 Evaluation of the Effectiveness of Using the Pseudo-Coloring Method  
### Subjective Assessment-Visual Assessment  
The visual assessment of images obtained by using the proposed pseudo-coloring method does not raise any doubts as to its effectiveness. Color images became clearer. They allow you to see more details that were not seen when using the \"Hot\" and \"Radar\" palettes. Additionally, the new images are friendlier to analyze. They do not force the user to strain their eyes more, and at the same time there is no noticeable human fatigue with the analysis of the received images, unlike the analysis of images in the form of reconstructed from compromising emanations (grayscale) or after using the \"Hot\" and \"Radar\" color palettes.  
The results obtained in the survey are presented in Table 4 (Figure 18) for Figure 10b, Table 5 (Figure 19) for Figure 10d, and Table 6 (Figure 20) for Figure 10f.  
The subjective assessment carried out shows a very large impact of individual human feelings on the assessment of images. At the same time, it depends on the type of the analyzed image. In each of the analyzed cases, the images obtained as a result of using the coloring algorithm proposed by the authors (\"Own\") received the highest marks.

Figure 18: Perceptual evaluation of images obtained in the process of pseudo-coloring the image from Figure 10a for the “Hot” and “Radar” palettes and proposed by the authors (“Own”): (**a**) women, (**b**) men, (**c**) women and men.  
The exception is the image shown in Figure 10a, for which the rating from the \"Men\" group for the authors' algorithm is slightly lower than the image obtained as a result of coloring with the \"Radar III\" palette.  
Due to the small group of observers, the subjective assessment made as part of the survey conducted by the authors should be additionally supported by the objective (analytical) assessment proposed earlier.
