Abstract:	恰可察覺失真度模型已被廣泛應用於透明浮水印技術。本論文提出一個基於離散小波轉換之恰可察覺失真度模型，以滿足浮水印透明度之需求。實驗結果證實運算速度有顯著的提升。 Based on the characteristics of human visual system, the just noticeable distortion (JND) model can be used to verify the transparency requirement of watermark. Specifically, watermark with intensities less than the JND values of an image can be added wit
