The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.

三步法哪l是一种较好的搜索算法，快速而且高效，它是在对数法的基础上对 其进行了改进，提出在每一步搜索后搜索步长均减半的算法。它基本保持了FS的 性能，但其计算量只有FS的10％左右。TSS在会议电视和可视电话中应用较多， 它通过三步搜索，逐步较小搜索步长。若最大搜索范围为士7，搜索精度取一个像 素，则步长为4、2、1，共需三步即可满足要求，从而得名。 (L three-step method which is a better search algorithm, fast and efficient, it is on the basis of the number of law be improved, made in every step of the search after the search step of the algorithm are reduced by half. It basically maintained the performance of FS, but the calculation is only about 10 of FS. TSS at the meeting on television and video telephony in the application of more three-step search through progressively smaller search step. If the maximum search range of disabilities 7, search for a pixel accuracy, the step size for the 4,2,1, a total of three steps to meet the requirements, thus its name.)

一个带用户界面的matlab语音合成和识别的程序，MainGuide01.fig通过提取MFCC，用dtw来计算实时录音和模板之间的最小距离，给出识别结果，并且给出波形图，频谱图，语谱图，基频和共振峰。MainGuide02.fig是语音合成程序，通过load一个wav文件用LPC，残差和pitch两种方式进行合成，并且能实时听合成语音的效果。注意用的是matlab2012b以上才能打开fig(This is an simple user interface program including speech recoginition and speech synthesis.MainGuide01.fig extracting MFCC and using DTW to calculate the minimum distance between the real-time recording and templates , the recognition results are achieved, and the waveform diagram, FFT result , spectrum diagram are shown. including Pitch and Formant Curve . MainGuide02.fig is a speech synthesis program, it load a wav file using LPC, synthesis by the residuals or by pitch two ways, you can listen to synthesized speech effect in the real time . You must ushe matlab version latest more than 2012b that could be OK )
