watermark detection

常见例句

Employing mean filtering process, the algorithm doesnt require the use of original signal for watermark detection.
利用均值滤波处理，算法在水印的检测过程中不需要使用原始信号。
Watermark detection is implemented by comparing the new difference of mean values of watermarked image blocks with the threshold values.
在水印提取时，计算分块的新的均差值并与所设门限进行比较，从而检测嵌入的原始水印值。
However, in many applications it needs an asymmetric scheme , where a private key is used for watermark embedding, and a public key is used for watermark detection.
而许多实际的应用都要求非对称的数字水印方案，即水印嵌入时使用私人密钥，水印检测时只需要一个公开密钥。
