HHT变换的EMD方法和希尔伯特谱的一些源程序，以及一些实例数据(HHT transform the EMD method and Hilbert spectrum of some of the source, and some examples of data)

功能：对矩阵A的左上角的m阶对角块作QR变换：先用Givens变换作QR分解A=QR， 再作相似变换A:=Q AQ=RQ. 输入: n阶HessenbergA，其中A(m+1,m)=0,m>2. 输出: 变换后的Hessenberg形矩阵A. 2 用基本QR算法求实方阵的全部特征值.(Function: the upper left corner of the matrix A, diagonal blocks of order m to QR transformation: first, to make QR decomposition using Givens transformations A = QR, re-similarity transformation A: = Q' AQ = RQ. Input: n-order HessenbergA, where A (m+1, m) = 0, m> 2. Output: transformed Hessenberg form matrix A. 2 matrix with the basic QR algorithm for all the characteristics of the value of truth-seeking.)

用MATLAB对指纹进行分割，二值化，特征提取以及匹配。希望对大家有用。(Using MATLAB on the fingerprint segmentation, binarization, feature extraction and matching. Hope to be useful.)

Region Growing algorithm

this is a code for viterbi in the forward mode

说明：  通过编程，利用变步长的求积公式求解积分，具有较高的精确度(By programming, the integral can be solved by the quadrature formula with variable step size, which has high accuracy.)
