水平均值滤波器的Matlab代码
 

如何在Matlab中对频谱图应用水平均值滤波器？

有很多方法。例如，您可以使用[URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/conv.html"]conv[/URL] 。

对于一维频谱图：

%# create some sample data spectrogram = randn(1,1000); %# row vector of length 1000 with random values %# define filter window windowSize = 5; %# size of filter window %# filter filteredSpectrogram = conv(spectrogram,ones(1,windowSize)/windowSize,'same'); 对于二维频谱图（和仅水平滤波器）

%# create some sample data spectrogram = randn(100,1000); %# 100 rows, 1000 cols of random values %# define filter window windowSize = 5; %# size of filter window %# filter filteredSpectrogram = conv2(spectrogram,ones(1,windowSize)/windowSize,'same');
