中文摘要：
本文针对人体肤色和黏膜颜色特点,建立一种室内自然光条件下的医学真彩图像采集分析的颜色恒常性模型.在LAB均匀色度空间中,对一维L＊空间进行线性影射,二维a＊b＊空间进行三角剖分影射和还原,建立了一种拓扑剖分影射TRM模型.通过对SG色标中13个肤色色标进行的校正还原,结果显示,TRM模型还原的颜色色差明显减小,离散度小,性能稳定.
英文摘要：
Aiming at the color features of human skin and mucosa,a color constancy model is established to collect and analyze medical true color images under natural light condition.In LAB color space,a TRM（topology resolve-map） model is established to restore these colors from the gathered images to standard values by linear mapping to the one-dimensional L＊ space and triangulation mapping to the two-dimensional a＊b＊ space.Via regulating and restoring the 13 skin colors in SG color codes,the experimental results show that the TRM model has good accuracy and stability and the differences of delta L,delta ab and delta E are dramatically decreased.
