Abstract
This work extends the watermarking method proposed by Kutter et al. [1] to increase the watermark decoding performance for textured or busy images. The proposed algorithm modifies watermark embedding rule to utilize image characteristics, like local standard deviation and gradient magnitude, in order to increase the decoding accuracy for busy images. The method does not need original image for decoding and controls the watermark embedding process at encoder site, resulting in a more accurate decoding.
