中文摘要建立了一种基于图像处理的快速瞳孔直径检测算法,运用此算法提取了反映阿片类药物成瘾人员与正常人对瞳孔光反射变化差异的3个特征值:绝对收缩幅度(absolute amplitude of contraction,AAC)、相对收缩幅度(relative amplitude of contraction,RAC)和收缩斜率(SCV,slope of contraction velocity);分别研究了成瘾、性别、近视、年龄、睡眠剥夺等因素对于这3个特征值的影响。不同性别、近视人员、睡眠剥夺人员与正常人之间的3个特征值均无显著差异,成瘾人员与之对比均显著减小。老年人相对于正常青年人,3个特征值都明显减小;与成瘾人员相比,仅在RAC值上有显著差异。结果表明,阿片类药物成瘾人员除了与正常人外,也与其他具有潜在影响瞳孔变化因素的非阿片成瘾人员在瞳孔对光反射的特征值上具有显著差异。该研究的实验数据为进一步建立基于检测瞳孔对光反射其直径发生变化的方法来快速、非接触地鉴别出阿片类药物成瘾人员提供了可靠的依据。
英文摘要An effective algorithm for detecting pupil size based on image processing was established.Three features reflecting differences between opiate addicts and normal subjects in pupillary light reflex were extracted by applying this algorithm,including absolute amplitude of contraction(AAC),relative amplitude of contraction(RAC) and slope of contraction velocity(SCV).Effects of addiction,sex,myopia,aging,sleep deprivation on the three features were studied.None of three features was found significant differences between sexes,myopia,sleep deprived and normal subjects.Only RAC increased significantly in aging subjects in comparison to opiate addicts,The features of pupillary light reflex in opiate addicts decreased significantly not only comparing with normal subjects,but the subjects with potential facts that may alter their pattern of pupil light reflex as well.Our study provided basic data for future establishment of a rapid,non-contact method in distinguishing opiate addicts from other subjects based on pupillary light reflex.
