Worldwide metaheuristic techniques are being used to find optimal solutions to different
optimization problems. Image watermarking is presently perceived as one such problem.
Several metaheuristic techniques, such as genetic algorithms, particle swarm optimization,
ant colony optimization, and the firefly algorithm have been successfully applied to
implement image watermarking. This chapter delves into the problem of developing a robust
and optimized watermarking scheme using a hybrid DWT–SVD transform. The singular …
