该技术将水印嵌入到视觉不太敏感的蓝色通道中，通过调制图像子块均值在映射区间上的分布，构建新的图像稳定特征，并实现水印的嵌入和盲检测。

Through modulating the distribution of block average over a mapping range, a new stable image character is built, watermarks are embedded and blind-detect is implemented.

车型的细节特征是通过图像分割后提取子块数目、颜色数目以及车窗比例等特征完成的。

The detail features which are the amount of blocks and colors and the ratio of window are distilled by the image segmentation.
