Examples
- Operating in the low and middle bands of the radio spectrum , one or two rf mems analog channels can create short - range ad hoc networks in any band where licensed users agree to rent , share or otherwise barter for radio spectrum
处于无线电频谱的中低频带时，只要是在使用者同意租用、分享或交换的频带上，一或两个rf微机电系统的类比频道，就能建立起短距离特定网路。 - One is the colorful watermark medical image electronic signature that based on the discrete wavelets transformation . in this method , using color medical images as the original image , a new watermark hidden algorithm , which uses mixed chaos sequences to preprocessing the electronic signature information , is presented . this algorithm transforms the color space , by changing wavelets ’ low frequency coefficient to embed the watermark in
其中一种是基于离散小波变换的水印彩色医学图像电子签名方案;在这个算法中,采用彩色医学图像为原始图像,提出利用混合混沌序列对电子签名信息进行预处理的新的水印隐藏算法,对真彩图像进行色彩空间转换,通过改变小波低频系数将水印嵌入到小波的低频带。
