Study on the functional model of color calibration of tongue diagnosis based on mobile phone terminal

Objective:To explore the establishment of a function model for color calibration based on the tongue image of a mobile phone terminal.Methods:In this study,the TDA-1 small tongue imager was used as a reference standard,and the standard color card L^*a^*b^*color value collection and analysis were carried out through 5 different types of mobile phone devices under the optimal conditions of the experiment.Then we built and optimized the BP neural network model.Results:Analyze the average color difference value obtained by the tongue diagnostic instrument and different mobile phones for shooting standard color cards,and screen the P brand mobile phones for clinical sampling.Corrected by BP neural network,the difference between tongue quality,tongue fur color value and standard value was significantly reduced(P<0.05).After correction,ΔE was significantly reduced(P<0.01),and the color boundary was clear.Conclusion:The predicted output values of this model are close to the L^*a^*b^*values obtained by the TDA-1 small tongue imager.So the correction model can effectively perform color difference correction to improve the accuracy of the color value about the tongue image based on mobile phone.
