[Application of kalman filtering based on wavelet transform in ICP-AES].

Kalman filtering is a recursive algorithm, which has been proposed as an attractive alternative to correct overlapping interferences in ICP-AES. However, the noise in ICP-AES contaminates the signal arising from the analyte and hence limits the accuracy of kalman filtering. Wavelet transform is a powerful technique in signal denoising due to its multi-resolution characteristics. In this paper, first, the effect of noise on kalman filtering is discussed. Then we apply the wavelet-transform-based soft-thresholding as the pre-processing of kalman filtering. The simulation results show that the kalman filtering based on wavelet transform can effectively reduce the noise and increase the accuracy of the analysis.

[A digital tongue image analysis instrument for Traditional Chinese Medicine].

A digital tongue image analysis instrument (TIAI) based on computer for Traditional Chinese Medicine is introduced. Some of the key techniques, including the image acquiring condition and method, the evaluation of tongue characters, and the management of tongue image data, are discussed as well. TIAI can provide a non-invasive, quantitative, and objective analysis approach and enhance the theory level and practical ability of the Traditional Chinese tongue diagnosis.
