A Survey of Digital Image Watermarking Optimization Algorithms Inspired by Nature

Real world problems in the recent years have become more complex, hence more powerful optimization techniques are needed to solve these complex and unsolvable problems. These algorithms provide a protean and conditional solution. In this paper a survey of thealgorithms inspired by nature which can be used togenerate optimal watermarked image. Firefly Algorithm (FA), Modified Firefly Algorithm (MFA), Cuttlefish Algorithm (CA), Bat Algorithm (BA), Artificial Bee Colony, Seed Based Plant Propagation Algorithm, are considered to generate the optimal digital watermarking.
