    具體指示效能評估在觀察系統效能評估的層面上進行，用水聲設備截獲被打擊目標的概率來表示，為保障潛艇導彈攻擊目標指示組織指揮提供了科學的依據。
  3. A 3 - year - old male bulldog, riggs is a drooler with protruding teeth and a penchant for attacking noisy appliances, begging for crumbs and hopping on furniture

    三歲的公牛頭犬里格斯長著暴牙、流著口水、愛攻擊發出聲響的電器、總是搖著尾巴要麵包屑吃，還喜歡在傢具上跳來蹦去。
  4. Riggs hardly looks or acts like a beauty king. a 3 - year - old male bulldog, riggs is a drooler with protruding teeth and a penchant for attacking noisy appliances, begging for crumbs and hopping on furniture

    三歲的公牛頭犬里格斯長著暴牙流著口水愛攻擊發出聲響的電器總是搖著尾巴要麵包屑吃，還喜歡在傢具上跳來蹦去。
  5. In order to adapt the scheme to both the color image and the gray image, while embedding the watermarking into the image, the scaling factors are determined by the local luminance feature and texture features of the image. it can improve the embedding strength and the watermarking robustness. from the experimental results, the stego - images are extremely robust to common image processing such as median filter, jpeg compression and denoising after adding the stochastic noises

    2 、提出了一種新的基於小波變換和紋理特徵的數字水印演算法，該演算法依據從圖像小波域提取出的紋理特徵來選取水印的嵌入位置，較好地利用了圖像的紋理區域，既能掩蔽較多的噪聲，又能較好地抵抗jpeg壓縮等一般性攻擊，調節了數字水印技術中存在的不可見性與魯棒性之間的矛盾。
  6. A new type of blind watermarking technology, which has the advantage of adopting watermarking embedding algorithm is introduced based on wavelet transform and cosine transform, so the original image isn ' t necessary when picking up watermarking and the transparency and robustness of digital watermarking system is well fulfilled, the attack in the forms of noise, median filtering and compress can be withstood, and high pass filtering and low pass filtering can also be endured

    摘要詳細介紹了基於一種新型的基於小波變換和餘弦變換的盲水印數字水印技術，這種方法的一個顯著的優點就是採用水印嵌入演算法，提取水印的時候不需要原圖象，能夠很好的滿足了數字水印系統的透明性和魯棒性，能夠經受住加入噪聲、中值濾波、壓縮等方式的攻擊，並且還能夠經受住高通濾波和低通濾波。
  7. Attack the watermarked image through adding noise, filter, and jpeg compress. in the extracted watermark from the attacked image, the important part, which is embedded into frequency domain, has good robustness

    對含水印圖像進行噪聲、濾波、 jpeg壓縮等攻擊，確保了dct域中的重要部分有良好的魯棒性。
