embed the watermark的用法和样例：
例句
- The length of the watermarking is adaptive to the richness of the image veins.
根据图像的纹理丰富程度来自适应地选取嵌入水印的长度。 - The simulation results show that with the proper threshold, the reference watermark can be used to detect the embedding watermark, but other embedding watermarks cannot.
仿真结果表明，选择恰当的判决门限，参考水印能正确地检测嵌入水印，而由参考水印生成的其它嵌入水印却不能实现水印检测。
