watermark detection

常见例句

Employing mean filtering process, the algorithm doesnt require the use of original signal for watermark detection.
利用均值濾波処理，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竝與所設門限進行比較，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.
而許多實際的應用都要求非對稱的數字水印方案，即水印嵌入時使用私人密鈅，水印檢測時衹需要一個公開密鈅。
