Garbor filter is famous for its approximation to the characteristic of Cortex in human vision system. The state-of-the-arts advancement in computer vision application demonstrates the success and promissing of this technique. This directory contains the codes for Gabor filtering and texture feature extraction. The strategy of constructing the Gabor filter bank is based on the accompanied paper included in the subdirectory.(Garbor filter is famous for its approximation to the characteristic of Cortex in human vision system.

It enables users to input a time-series of 2-D velocity field data (e.g., DPIV measurements or CFD calculations) and compute the corresponding finite-time Lyapunov exponent (FTLE) fields, which Lagrangian Coherent Structures (LCS) suchas vortices and fluid transport barriers can be identified.

Numerical solution for solving algebraic linear equations.

说明：  频谱图，做工程振动，频谱分析。绝对可运行！(spectrogram in vibration analysis)

这是用matlab写的dct代码用于图像的信息的隐藏和提取。。部分老师写的哦。(This is used to write the DCT matlab code for the image and extract the hidden information. . Oh part of the Writing Teacher.)

数值方法解方程组AX=B（LU分解），过程分3步，首先，分解系数矩阵A=LU，然后，解LY=B，最后再求UX=Y 另一种是直接求解的（2.1）(Numerical method to solve the equations AX = B (LU decomposition), 3 step process, first of all, the decomposition of the coefficient matrix A = LU, then, Xie LY = B, and finally seek UX = Y another directly solving (2.1 ))
