本文利用近红外光谱(NIRS)技术研究了脑血流与图像质量的关系。测量脑血流数据，并将其应用于图像质量评价。为了证明测试对象承认测试图像的质量下降，我们通过问卷进行了主观评估测试。结果显示，所有受试者都承认质量下降。我们发现，当受试者观看运动图像时，额叶中的氧合血红蛋白增加，当图像质量下降时，血液流动的变化更大。我们认为，近红外光谱可以有效地应用于图像质量评价领域。
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.
