Figure 5
An example of the color maps that represent the correlation between advancing age and the morphological changes in teeth, prepared by generating virtual teeth images when the subject was younger or older using the developed VAE and linear regression model. The images in the first row are virtual images generated by controlling the latent variables of first molar teeth. The images in the second row are images in which the pixel difference between the original image and the virtual image generated by increasing or decreasing the age is expressed as different colors in the form of a diverging color map. Here, colors with higher intensity indicate that the corresponding regions have a stronger correlation with age. The images in the third row are those generated by overlaying the obtained color maps onto the corresponding teeth images to allow a quantitative analysis of the morphological changes in teeth with age.
