The HVS model is based on the computation of the noise visibility function (NVF) and embed at the texture and edge region stronger embedded watermarks.

模型基于噪声可见性函数(NVF)的计算来决定水印嵌入强度，使水印更多的嵌入到图像的纹理和边缘区域。

A video sequence possesses not only spatial properties like images, such as color, edge, texture, but also temporal properties, namely, the motion information.

视频数据除了具有与图像一样的空间特性外(如颜色、边缘和纹理等)，还具有时序特性，即视频中存在运动信息。
