“Selecting Optimized feature region set for digital image using Algorithm” is discussed here. Enhancement of a digital watermarking algorithm is denoted by the robustness of embedded watermarks against various attacks. Method based on the simulated attacking and the GA-based MDKP solving procedure is developed to select the most adequate feature regions for robust digital image watermarking under the constraint of preserving image quality. Finally, we select most robust region from selected primary feature regions using generic algorithm.
