Sažetak
There exist continuous effort to develop new or improve existing watermarking methods. The main goal of this paper is to give preliminary insight of the applicability of the Gray Component Replacement (GCR) masking to frequency domain based watermarking scheme. The use of GCR masking can potentially increase the performance of a watermarking method by improving robustness or imperceptibility of an embedded watermark. The applicability of GCR masking is tested by extending well known watermarking method with GCR masking capability and comparing the imperceptibility of the embedded watermark before and after GCR masking. Results show that GCR masking can substantially increase the PSNR value of the watermarked image.
