面诊是中医特色诊法之一,通过观察面部的变化可探知人体气血的盛衰和五脏六腑的虚实变化。长期以来,面诊主要依靠中医医师的个人经验进行,缺乏客观化的诊断方法和标准,因此面诊的客观化和量化研究具有重要的意义。随着计算机技术与中医... 面诊是中医特色诊法之一,通过观察面部的变化可探知人体气血的盛衰和五脏六腑的虚实变化。长期以来,面诊主要依靠中医医师的个人经验进行,缺乏客观化的诊断方法和标准,因此面诊的客观化和量化研究具有重要的意义。随着计算机技术与中医学研究的紧密结合,计算机辅助诊断已经成为临床医学中不可或缺的一部分。就中医面诊客观化研究中的计算机识别技术及其临床应用做一综述,并根据研究中存在的问题提出一些建议。 展开更多

A novel algorithm for voice conversion is proposed in this paper. The mapping function of spectral vectors of the source and target speakers is calculated by the Canonical Correlation Analysis (CCA) estimation based on Gaussian mixture models. Since the spectral envelope feature remains a majority of second order statistical information contained in speech after Linear Prediction Coding (LPC) analysis, the CCA method is more suitable for spectral conversion than Minimum Mean Square Error (MMSE) because CCA explicitly considers the variance of each component of the spectral vectors during conversion procedure. Both objective evaluations and subjective listening tests are conducted. The experimental results demonstrate that the proposed scheme can achieve better per- formance than the previous method which uses MMSE estimation criterion. 展开更多
