Table 5: Results of factor analysis. The results of the factor analysis are shown in Figures 3 and 4. The explained variances of image restoration function, image editing function, style transfer and migration function, and multi-layer image restoration function are 28.017%, 23.254%, 20.705%, and 15.430%, respectively, which shows that the explained variances in the image restoration function are higher than those of the other three indexes; the explained variances of visual harmony, quality of service, interaction, media applicability, and pattern recognition are 20.784%, 18.333%, 15.968%, 15.058%, and 14.755%, respectively.
