基于SURF和归一化的数字图像零水印算法
A Digital Image Zero-watermarking Algorithm Based on SURF and Normalization
摘要
Abstract
The zero-watermark algorithm is more complex currently in calculation and can not be applied to real-time systems. SURF al-gorithm is the algorithm of scale-invariant,rotation-invariant and better performance,and it has the small amount of calculation,it is suit-able for application in detection speed platform. Image normalization aims to get the standard images after the same parameters normalized what had suffered some processings or attacks. Owned by one and the SURF feature,the zero-watermark is not only able to resist conven-tional attack,such as scaling,rotation,JPEG compression and so on,but also supports real-time requirements of the system. The experi-ments show that compared with other algorithms,the algorithm has good robustness and efficiency and can be applied to the platform which has detection speed requirements.关键词
