时频分析工具箱，找了好久的，用起来不错的(Time-frequency analysis toolbox, looking for a long time, and using up a good)

Corner detection for camera calibration using a 3D calibration object. To get corners one must to define a 6point ROI. The corners will be detected inside ROI and will be put into a vector.

FIR数字滤波器在工程上运用广泛．窗函数法设计FIR数字滤波器是典型的设计方法。目前。相关课程的教科书对窗函数法设计FIR 散字滤波器这部分内容讲解不够细致，学生掌握感到有难度。本文针对窗函数法设计FIR数字滤波器的相关问题．即数字滤波器与模拟样本 滤波器的关系、截断点如何取值和数字滤波器的线性相移特性，结合实例进行分析。并借助Matlab仿真软件对设计进行了分析和验证．(FIR digital filters widely used in engineering. Window method is a typical design FIR digital filter design methods. Present. Related courses textbooks window functions designed FIR filter scattered words to explain this part carefully enough, students are difficult to master. This window function method for the design of FIR digital filters related issues. Samples of the digital filter and analog filter between values and the cut-off points to the linear phase shift digital filter characteristics, with examples for analysis. And using Matlab simulation software design analysis and verification.)

用Viterbi algorithm筛选经过含白噪声的信息。equalizer为采用Viterbi algorithm，有效减少ISI(码间串扰)，detector为简单的检验器。对比两者的误码率。信息数量为10001bit(using Viterbi algorithm method selecting the data. compared with simple detector. data length are 10001bits. Viterbi algorithm can reduce the affect of ISI （intersymbol interference）)
