Gaussian Filter Based Image Watermarking

Abstract:

We present a spatial domain image watermarking method based on a Gaussian filter: it assumes that, in a watermarking method based on the modifying blue image pixels, if the watermark to be embedded within a local area is controlled by a Gaussian distribution, a Gaussian filter based watermark extraction will be the most fitted method used to obtain the highest accurate version of extracted watermark. Experiments show the accuracy of the extracted watermark in terms of NC was notably improved from our previous method. The robustness against attacks was also improved.
