| Outline of Final Research Achievements |
The aims of this study are to identify the wavelength band suitable for remote blood glucose measurement by multi-wavelength spectroscopy and to estimate blood glucose levels using facial images measured in the identified wavelength band. In the first year, a comparison of estimation accuracy of blood glucose levels based on facial images measured in visible, near-infrared, and infrared bands was performed. As a result, the accuracy based on facial images measured in the near-infrared band was the highest. In the last year, a comparison of estimation accuracy of blood glucose levels based on facial images measured in the first near-infrared region and the second near-infrared region was performed. As a result, the accuracy based on facial images measured in the first near-infrared region was higher. These results suggested that the wavelength band suitable for remote blood glucose measurement is the first near-infrared region.
