Abstract
Watermarking techniques use different ways to embed the watermark within the host. They use different strengths (scaling factor) of the watermark when embedding it. In this paper we have optimized the single scale factor of the watermark using Particle Swarm Optimization (PSO) to yield a watermarking scheme with the best possible robustness(highest Normalised Cross-correlation), keeping the scheme as imperceptible as possible.
