摘要：Digital watermarking has rise as a new research area for preventing illicit copying and duplication. In this papertwo methods 3-level DWT & Local Binary Pattern (LBP) algorithm for watermarking in digital images are discussed. In orderto compare the robustness of both algorithms noise attack is used
