Tongue Image Acquisition Device Based Color Reproduction and Associated Improvements
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

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.
