The representation method is different from conventional models in that some information that is sensitive to human eyes is enhanced by using local variance distribution. It encodes the local variance distribution of different channels of a color image into the three imaginary parts of a quaternion. The distance between the singular value feature vectors of the source image block and the distorted image block which are described by quaternion matrices is calculated. The experimental results show that the assessment results of the proposed assessment method are more consistent with the Human Visual System than those of the conventional assessment methods.   Genotoxicity in Vinyl Chloride-Exposed Workers and Its Implication for Occupational Exposure Limit 期刊论文 AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, 2011, 卷号: 54, 期号: 10 作者:  Wang, Wei;  Qiu, Yu-Lan;  Jiao, Jie;  Liu, Jing;  Ji, Fang 收藏  |  浏览/下载：3/0  |  提交时间：2019/12/19 vinyl chloride monomer  cumulative exposure dose  cytokinesis-block micronucleus assay  benchmark dose  occupational exposure limit  genotoxicity  risk assessment
