中医望诊图像信息标准量化与显示复现
|
摘要
针对中医望诊信息系统普遍存在数据不规范、显示效果差异大的问题,指出目前望诊图像数据采集与描述的误区,给出信息规范化的解决途径.认为6 500 K日光模拟光源可作为望诊信息系统的标准评价光源;提出采用色度空间作为数据描述的标准空间,通过基于成像模型的图像数据颜色修正方法实现原始图像数据向标准空间数据的转换,达到标准化数据描述的目的,由此形成了望诊图像采集与描述的标准化框架及评价方法,实验结果表明该框架可使不同望诊图像信息系统达到较高的数据一致性;最后,结合显示器颜色属性测试和修正方法,实现了显示图像的颜色复现.
At present,in the inspection information system of traditional Chinese medicine,the data universally lack normalization,and display effects are usually varied. According to the above problems, the misunderstandings of inspection image acquisition and standard expression are pointed out,and the solutions to solve the problem of information normalization are presented. Daylight simulator with 6 500 K color temperature is considered the standard light source for inspection information systems; it is proposed that CIE color spaces can be regarded as standard representing space for inspection information,and the transform from original image data to standard representing space can be achieved by color correction; and the standard framework of inspection image acquisition and description is formed through the light environment standardization and image data correction. Experimental results show that this framework can achieve high consistency among different inspection information systems. Finally,combined with color performance measurement of display and color correction methods,color reproduction for image display is achieved.
