工程图中的抗扫描打印技术研究

Technology Research on the Anti-scan Printing in the Drawings

通过对抗打印扫描数字水印领域的研究状况进行归纳和总结,分析了打印扫描失真对工程图的影响,在对打印扫描前后进行对比后,寻找抗打印扫描前后的特征不变值。

Summarized and induced by the research status in the field of confrontation print scan digital watermarking, and analyzed with the impact on the drawing by the print scanning distortion to look for the same characteristics of scanning values before and after anti-print.
