摘　　要：目的:常规手腕骨Tw3骨龄检测法不适用于骨骼停止发育的成年人的年龄检测,而人体皮肤在成年之后变化特征明显,通过求解皮肤特征参数与年龄关系,从而达到针对成年人年龄检测的目的。方法:采用医学图像处理技术,无损检测并提取皮肤图像的量化参数凹凸度和信息熵,采用统计方法分析这些特征参数与年龄之间的关系。结果:成年人的年龄与皮肤图像的凹凸度呈负相关;与信息熵为正相关。结论:实验研究表明通过皮肤特征参数能够检测成年人年龄,克服了传统单一运用骨骼检测年龄的局限,扩大了年龄检测范围。Objective： TW3 method can not be applied to age determination of adults because skeletal development stops after Childhood and Adolescence.This paper develops a new method to evaluate adult age by the fact that the human skin implies age information.Methods： Some advanced medical image processing technologies are used in the age evaluating system to extract quantization parameters of roughness and entropy on human skin image.Results and Conclusions：The Correlation between Roughness and age is negative,the Correlation between entropy and age is positive.So the relationship of the quantization parameters and age can be used to evaluate adult age theoretically.The conventional TW3 age evaluating system that uses skeleton is applied to children,while this age evaluating method that use human skin can evaluate adult age which have a wide range age spectrum.
