| Abstract | In this paper is evaluated the effect of image enhancement filters on the watermark detection rate. State-of-the-art watermarking methods are still very sensitive to complex degradation attack such as print-scan process, so the detection rate of a watermark method decreases considerably after such an attack on a watermarked image. Therefore, to improve the detection rate, the degradation of the image is reduced by using image enhancement filters. A dataset of 1000 images was watermarked, printed and scanned for the experiment. Scanned images were enhanced by means of an unsharp filter and blind deconvolution filter. The watermark detection rate was measured and compared before and after the enhancement. The results show that the enhancement filtering improves the watermark detection rate by almost 10 %. |
