Research on Color Calibration Method Based on Artificial Neural Network
基于人工神经网络的彩色校正方法研究

Physical characteristic of Chinese medicine tongue is mainly reflected by colors, in the research of tongue analysis instrument, the most important and hard technique is how the colors to be measured and how to keep the accordance and repeated of colors between the different devices. In this paper, the structure of tongue analysis instrument is briefly described. Choice and design of illumination is given, and the color calibration method to camera and CRT using artificial neural network is presented.
