查询词典 radon measure

The method first embeds watermark into the geometric invariant Fourier-Mellin domain of an image to weaken the geometric distortion, brought by printing process, of the watermark in presswork, and the image is then used to create presswork via a legal printing process. Secondly, the method rectifies rescanned image from the presswork by using Radon transformation and the embedded watermark in it is detected. Since there is an obvious difference between the destruction degrees of the watermark caused respectively by legal and pirated printing process, we can judge whether a copy of presswork is valid or not just by computing the ratio of the successfully derived watermark and comparing it with a predefined threshold.

该方法先将水印嵌入到具有几何不变性的Fourier-Mellin域中，以削弱正版印刷过程中的几何失真对水印的破坏；再利用Radon变换对由扫描印刷品所获得的图像进行矫正，并从图像中提取嵌入的水印信息；由于正版和盗版印刷过程对水印的破坏程度区别明显，该方法最终通过计算水印提取的正确率来度量这种破坏，并将其与预先制定的阈值进行比较来判定印刷品的正伪。
