Volume : XIV, Issue : III, April - 2024 DIGITAL WATERMARKING IN THE FRACTIONAL HARTLEY DOMAIN Vasant Gaikwad, - DOI : 10.9780/22307850, By : Laxmi Book Publication Abstract : Digital watermarking aims to balance quality and robustness, crucial for effectiveness, despite their inversely proportional nature. Spatial domain mbedding enhances quality but diminishes robustness, whereas frequency domain embedding prioritizes robustness over quality. Utilizing common image transforms like DCT, DFT, and DWT improves robustness, enabling multiple watermark embeddings. The proposed non-blind watermarking algorithm utilizes the DFRHT transform for integration into host and watermark images, evaluated through coefficient addition.
