medianfilter.m

自动语音识别源码对非特定人的孤立词语音识别算法 进行研究。考虑到语音识别技术在嵌入式系统处理能力较弱、存储空间有限的问 题上进行算法的选择和优化

function out = medianfilter(input, order, overlap)
% MEDIANFILTER Median filter for an input vector
%	Usage: OUT = MEDIANFILTER(INPUT, POINT_N);

if nargin<3, overlap=order-1; end
matrix = buffer2(input, order, overlap);
out = median(matrix, 1);
