| 1. | In dwt , we extended one watermark pixel into a block
不仅在中频嵌入水印，在最低频中也嵌入水印。 |
| 2. | Compared with still pictures , video watermark technology need high requirements
在视频中嵌入水印比在静止图像中嵌入水印难度更大，要求更高。 |
| 3. | A bit stream control mechanism is introduced to maintain the data rate after the embedding manipulation
采用位流控制机制来保证嵌入水印后的数据率。 |
| 4. | This algorithm can embed the watermarking ( secret information ) in the audio cover to the maximum extent
该算法能最大限度地在音频载体中嵌入水印(机密信息) 。 |
| 5. | The embedding process is completed in dwt domain by exploiting the characteristics of hvs
该算法利用人类视觉系统( hvs )的特征在离散小波变换( dwt )域中来嵌入水印。 |
| 6. | Watermark ' s detection does n ' t need the original unwatermarked image and thus it is a blind scheme
在水印检测阶段，不需要未嵌入水印的原始的图像，因而是盲算法。 |
| 7. | It equals to embedding one pixel many times . using the origial image texture , the watermark is performed
利用像素扩展技术重复嵌入水印提高鲁棒性，增强水印提取的可靠性。 |
| 8. | Two image watermarking methods embed watermarks into transform domain using the multi - scale characteristic of wavelet
