Human vision system ( hvs ) theory is very important for image watermarking technology 人类视觉系统理论在图像数字水印技术中有着非常重要的应用。
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。
So a fr algorithm is designed by fusing holistic and local features in subspaces , which is inspired by human visual system ( hvs ) 本文模仿人类视觉系统的特点,提出了融合局部和整体特征子空间的算法。
Watermarking algorithm of good perception property can be designed by making full use of vision masking of hvs 进行水印嵌入时,充分利用人类视觉系统的视觉掩蔽特性,可以设计出感知性能良好的数字水印算法。
This thesis discusses the human visual system and its applications in the field of information hiding in terms of digital images 本文主要针对数字图像,探讨了人类视觉系统( hvs )及其在信息隐藏方面的应用。
