Matlab code for basic image processing. Filtering, color inversion etc

感知准则梯降法求线性判别函数权向量的算法(using perceptual criterion to find weightvector of a linear decision function)

基于图形化编程语言LabVIEW8.6的虚拟频谱分析仪，主要由信号发生器、数字滤波、参数测量、频谱分析和谐波分析构成，可实现对采样信号的显示、分析等功能.(This program designs the virtual spectrum analyzer based on graphical programming language LabVIEW8.6, the spectrum analyzer is mainly by the signal generator, spectrum analysis and digital filtering, parameter measurement, harmonic analysis, which can realize the sampling signal display, analysis, and other functions. Reliable operation, good performance.)

用matlab编写的关于流场测速的一个Demo,处理速度较快、匹配位置准确。(The URAPIV Toolbox contains a set of command-line functions to import, post-process and analyse 2D vector fields from LaVision s DaVis PIV (particle image velocimetry) software. It enables to handle and perform operations over large amount of velocity fields, and to produce high-quality vector/scalar outputs. )
