New approach to scanning objects of illumination

Color compensation procedure. The whole scan takes hours to capture thousands of spectral channels, pixel by pixel. Thus, the image is affected by variations in natural illumination during the scan. The proposed approach includes an extra scan on a single column, which takes only dozens of seconds so that the illumination variation is negligible. By comparing both scans, the approach allows us to determine the variation component during the scan, and use it to compensate for the variations. Credit: Takuya Funatomi

Scientists from Nara Institute of Science and Technology created a new approach to compensate for variations in illumination while …
