%X As a solution to counter geometrical attacks,a localized image watermarking algorithms embed the watermark into each local regions referring to image features. To redetect the local regions for embedding the watermark in the watermark detection process,the feature as the reference should be robust. The scale invariant feature points are used as the reference to synchronize the watermark. To make the distribution of the reference even and stable,the references are selected out of the scale invariant points b...
