Invariant domain based watermarking using Riesz Transform

Digital image watermarking techniques are sensitive to geometric distortions such as scaling translation and rotation. These distortions make the watermark desynchronized which make it impossible to detect the embedded watermark. To solve this problem we developed a Riesz Transform based invariant d...

description Digital image watermarking techniques are sensitive to geometric distortions such as scaling translation and rotation. These distortions make the watermark desynchronized which make it impossible to detect the embedded watermark. To solve this problem we developed a Riesz Transform based invariant domain. Riesz transform is scale and shift invariance.The proposed domain does not need resynchronization step. Moreover unlike majority of invariant domain based techniques our technique enable blind watermark detection by eliminates the need of the original image in the watermark detection. Experimental results confirm the proposed technique is more robust than other techiques.
