基于颜色空间的尿毒症诊断研究

Diagnosis of uremia patients based on color space

由于传统甲诊易受到外界客观因素以及医生主观因素的影响,提出了一套甲象客观采集与信息分析相结合的中医甲诊系统用于尿毒症患者甲象客观化研究。采集并分割了15例尿毒症患者甲象正面照和侧面照,探究维持性血液透析前后甲色变化以及血红蛋白值与各色彩空间数值之间的关系等问题。利用相关分析和多元回归分析等统计学手段,对尿毒症患者血红蛋白值与维持性血液透析前后色彩空间值的关系进行了分析。实验结果表明,尿毒症患者血红蛋白值与多个色彩通道数值有一定的相关性,透析前后多个通道有显著变化,并建立了相关的多元回归方程。

Since traditional nail diagnosis is susceptible to objective factors such as illumination,medical experience,etc.,a nail diagnosis system of traditional Chinese medicine which combines objective nail image acquisition with information analysis is proposed and applied to the clinical research of nail diagnosis of uremia patients.Fifteen nail pictures of uremic patients were collected and segmented.The color information of nails was extracted.The relationship between the hemoglobin values of uremic patients and the values of color space before and after maintenance hemodialysis was analyzed by correlation analysis and multiple regression analysis.The experimental results show that the hemoglobin value of uremic patients have certain correlations with multiple color channels;before and after dialysis,there are significant changes in multiple channels;and the related multiple regression equation is established.
