| 4. | Theoretical analysis indicates that error probability of detector is independent of image itself , but only relies on the length of embedding watermarks and embedding strength factor 理论分析表明:检测器的误检测概率与图像本身无关,只取决于嵌入水印长度和嵌入强度因子。 |
| 5. | The first method is an improved dct - based private watermarking algorithm . the embedment intensity of watermarking is enhanced by the quantization of the originality carrier image 一个是在分析原有的明文水印算法基础上,通过对原始载体图像进行量化处理来增强水印的嵌入强度。 |
| 6. | Choose the frequency from 14 to 16 bark as the embedding positions which below the masking threshold . then change the dct coefficient with the certain strength of 选用中低频14 16bark段在掩蔽阈值以下的频率分量作为嵌入点,对该嵌入点的dct系数以一定嵌入强度作修改来实现秘密信息的嵌入。 |
| 7. | Embedding is selectively done in 8 x 8 blocks whose standard variance is less than the average of 8 - neighbor connective blocks " , and strength factor is determined by local image contents 水印有选择性地嵌入在那些标准方差小于8 -邻域方差均值的8 8块内,嵌入强度因子由图像局部内容确定。 |
| 8. | We adjust the strength of embedded watermark in according to the visual model in the ridgelet domain . experimental results show that our algorithm is very effective . performance improvement is obtained 论文根据小脊变换域中的视觉模型,按照小脊变换域中计算出水印嵌入强度的权重,用扩频的方法来嵌入水印信息。 |
| 9. | The original image was not required for extracting the embedded marks . a method to construct " zero - watermarks " " zero - watermark " is a new concept that donot change the original image during watermark embedment 但由于“零水印”和传统的水印相比,没有嵌入强度,因此如何构造一个强壮的“零水印”是一个较难的问题。 |
| 10. | Then propose an adaptive color image watermarking algorithm based on dct , which adaptive adjusts embedding threshold using the feature of hvs and ratio of rgb in 8 x 8 block , and embed watermarking in rgb channels 提出了一种新数字水印算法,通过dct变换来进行嵌入,利用hvs特性对图像进行分类,根据8 8图像块中rgb的比例来自适应地调整水印嵌入强度,在rgb颜色分量中嵌入水印。 |
