图像频域滤波，用matlab实现了在图像频域中通过Butterworth陷波器消除周期性噪声干扰信号。(Image frequency domain filtering using matlab achieved in the frequency domain image by Butterworth notch filter to eliminate periodic noise signal.)

二维高斯制式的TE波基于FDFT方法的Matlab仿真程序！(TE standard two-dimensional Gaussian wavelet FDFT methods in Matlab simulation program!)

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.)

这个是图像轮廓提取的matlab程序，而且提取完后还能把所有轮廓用不同颜色分开存放到轮廓矩阵cell中，方便用户对感兴趣的轮廓进行操作--张璐奉献(This is the matlab image contour extraction process, but also exhausted all the contours extracted with different colors kept separate from the profile cell in the matrix, user-friendly to operate the contours of interest- Zhang Lu dedication)

自己按照TPAMI文章编写的approximate pairwise accuracy criterion (aPAC)。已测试无误，并提供该代码所对应的文章。(This matlab code is writtern by myself,namely approximate pairwise accuracy criterion (aPAC)。The paper corrsponding to code is also provided.)

用于改进的FSC算法，求取特征基因，很好的算法。(FSC improved algorithm for obtaining genetic characteristics, good algorithm.)

matlab code for implementation in gabor

This tutorial white-paper illustrates practical aspects of FIR filter design and fixed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass filters, but many of the results apply to other filter types as well. The tutorial focuses on practical aspects of filter design and implementation, and on the advantages and disadvantages of the different design algorithms. The theory behind the design algorithms is avoided except when needed to motivate them.
