代码说明:

本代码针对正常非正常开门(指盗窃开门等声音)的声音进行识别的问题,通过matlab的sound和plot采集到了正常和非正常开门的声音信号和声音波形图,附件中有正常开门声音(如正1.mat),非正常开门声音(如非1.mat),各40次开门,共80次开门声音数据。将这些数据利用matlab的load函数载入到计算机内存,内存中变量有Fs和y等变量,其中Fs为采用频率,y为采用数据,通过建立数学模型将函数关系表示出来,并利用合适的时域或(和)频域特征表达声音信号,建立出特征向量.

    说明:  离散信号Gabor展开的理论及实现颇为繁琐。其中包括离散Gabor变换的标架理论、周期序列的离散Gabor变换、非周期序列的离散Gabor变换以及各种快速算法等。此程序给出给出了一个线性调频信号的Gabor变换。(Gabor expansion of discrete signals and the realization of the theory is quite cumbersome. Including discrete Gabor transform frame theory, the periodic sequence of discrete Gabor transform, non-periodic sequence of discrete Gabor transform and a variety of fast algorithms. This procedure gives a linear FM signal is given the Gabor transform.)
