This work considers a system of visual tracking of football players, which esteem the trajectories 2D in sequences of images captured for fixed cameras, installed around of a soccer field. The tracking allows to determine diverse parameters as, for e

1)football.m简单地以阵列形式显示一副图； 2）pre.m是心音信号过滤归一化预处理的过程； 3）wavlet.m是用db6小波进行信号的分解和重构，且求包络能量函数； 4）path.m是利用KKT条件的路径跟踪法，用于求解二次规划问题； 5）LRmmse是MIMO通信中常用检测方法，结合了最小均方误差准则和格基规约的知识。-1) football.m simply displays a graph in an array 2) pre.m is the proc

实现了对足球比赛中球员的追踪和检测，具有很强的实时性和针对性(Achieved football player tracking and testing, with strong real-time and targeted)
