watermark detection

常見例句

Employing mean filtering process, the algorithm doesnt require the use of original signal for watermark detection.
利用均值濾波處理，算法在水印的檢測過程中不需要使用原始信號。
Watermark detection is implemented by comparing the new difference of mean values of watermarked image blocks with the threshold values.
在水印提取時，計算分塊的新的均差值并與所設(shè)門限進行比較，從而檢測嵌入的原始水印值。
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.
而許多實際的應(yīng)用都要求非對稱的數(shù)字水印方案，即水印嵌入時使用私人密鑰，水印檢測時只需要一個公開密鑰。
