基于小型舌象采集平台的颜色重现算法和结构改进的探讨

新型舌象分析仪体积小可便携，解决了卧姿病人舌象采集的问题，对中医临床诊断具有重要的意义。采集的原始舌图像颜色存在较大失真，必须经过颜色重现以保证舌象特征分析的准确度和可靠性。本文提出一种基于感兴趣色域的离线颜色重现算法，实验证明色彩的还原度有所提高。为了进一步提高小型舌象采集平台的性能，获取高质量的舌图像，改善颜色重现后的效果，本文对光源色温等重要指标进行了定量分析，重新标定了照明环境的多项参数，希望为今后小型舌象采集平台的优化设计提供参考。

Tongue Image Acquisition Device Based Color Reproduction and Associated Improvements

Tongue image analyzing instruments have increasingly become so small and portable that they can be used to collect samples from bedfast patients. This provides more opportunities for traditional tongue diagnosis, in both theoretical and practical context. To maintain the needed accuracy and reliability for tongue character analysis, a right color reproduction method has to be employed to reduce color distortions. In the study, an interesting gamut based off-line color reproduction method is used to enhance the color precision. In addition, to obtain a stable and high quality tongue image, authors have optimized some parameters to achieve a right illuminating environment and color temperature.
