  • IIR滤波器设计
    现有一个信号:x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的: 低通滤波器,滤除cos(2*π*n/3) 的成分,即想保留的成分为1+cos(π*n/4) 高通滤波器,滤除1+cos(π*n/4) 的成分,即想保留的成分为cos(2*π*n/3) 带通滤波器,滤除1+cos(2*π*n/3) 的成分,即想保留的成分为cos(π*n/4) 带阻滤波器,滤除cos(π*n/4) 的成分,即想保留的成分为1+cos(2*π*n/3) 1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器;画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。 (an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)

  • 光学传递函数 OTF
    程序的主要目的是获得光学传递函数,通过光程差获得光瞳函数,之后获得点扩散函数,最终得到光学传递函数。(The main purpose of the program is to obtain an optical transfer function, the pupil function obtained by the optical path difference, after obtaining the point spread function, the finally obtained optical transfer function.)

    一个多目标跟踪的matlab代码,里面附有说明文档。其中背景差分法可以实现实时更新。该代码在检测与跟踪少量目标时效果很好,但是跟踪目标大于8后,效果下降很多(A multi-target tracking matlab code, which accompanied by a document. One of the background difference method can achieve real-time updates. The code detection and tracking at the time a small number of very good goal, but follow-up after the goal is greater than 8, the effect of decline in a lot of)
