Sažetak
The research in this paper is centered around examining the possibility of using low-frequency ranges in the frequency domain for data embedding in images. Specifically, different frequency ranges will be tested to determine how they affect image quality and detection at the decoder. The goal is to determine the optimal frequency range for data embedding. Finding that optimal frequency range will lead to higher detection rates while keeping image quality stable, or, contrary, provide higher image quality while maintaining the same detection rates. The proposed steganography method is suited for printing, but in this research, tests are conducted in the digital domain exclusively. The results show that the method is able to maintain consistent image quality regardless of the frequency range. Detection rates suggest that only the lowest frequency ranges should be avoided, while other frequency ranges can be used with similar success.
