Abstract

In this paper we examine the relationship between Cerebral Blood Flow and image quality using Near-Infrared Spectroscopy (NIRS). We measured data of cerebral blood flow and applied it to image quality assessment. To prove that test subjects acknowledged the quality degradation of test images, we performed subjective assessment tests through questionnaires. Results showed that all subjects acknowledged quality degradation. We found that Oxy-Hb in the frontal lobe increased when a subject was watching a moving image and change in blood flow was higher when image quality was degraded. We argue that NIRS can be effectively applied in the field of image quality assessment.
