说明：  一本很透彻地讲解如何利用MATLAB来进行生物信号处理的外文电子书。(A very thorough to explain how to use MATLAB for biological signal processing foreign language books.)

函数注册在Matlab和C++接口中起着重要的作用。在介绍函数注册作用的基础上，详细分析了函数注册的过程及应当注意的问题，并给出了一种实现函数注册的最简单的方法。用实例展示了函数注册的具体实现过程。 (registration function in Matlab and C interface plays an important role. In introducing the role of the registration function on the basis of a detailed analysis of the function of the registration process and should pay attention to the problem, and gives a registration function to achieve the most simple method. Examples demonstrate the function of the concrete realization of the registration process.)

KPCA 的基本思想是将数据从输入空间映射到高维特征空间,然后在特征空间利用线性主成分分析方法计算主成分。本程序是KPCA的源程序，可实现调用。对于初学者或许有帮助。(The basic idea of KPCA is to map the data from the input space to high dimensional feature space, then in the feature space using principal component analysis method to calculate the linear principal components. This program is the source KPCA can achieve call. May be helpful for beginners.)

Example of a two-dimensional Gabor filterIn image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filter are similar to those of human visual system, and it has been found to be particularly appropriate for texture representation and discrimination. In the spatial domain, a 2D Gabor filter is a Gaussian kernel function modulated by a sinusoidal plane wave. The Gabor filters are self-similar – all filters can be generated from one mother wavelet by dilation and rotation
