：利用小波分块思想，结合Arnold 变换算法，提出了一种基于小波分块的水印算法，并且利用人类视觉系统的掩蔽特性，使 水印的不可感知性和鲁棒性得到很好的统一-: The use of wavelet blocks thinking, combined with Arnold transform algorithm, a block of the watermark based on wavelet algorithm, and using the masking properties of

基于Labview的声音检测技术CAA文献，可鉴别人声，运用了Matlab小波分析。-Labview-based voice detection technology CAA literature, can identify the human voice, the use of Matlab wavelet analysis.
