In this work, we proposed a high-capacity robust watermarking scheme for color images. Based on integer wavelet domain (IWT), the proposed scheme utilized the idea of computing the offset of two square-root-values, a number of data bits can be embedded in a host image. Simulations indicated that our method did provide a large hiding-storage while the perceived quality is good. Further, the proposed method is tolerant of various attacks such as brightness, cropping, edge sharpening, blurring, ip horizontal, inversion, and rotation. Additionally, the payload for the proposed method is larger than that for existing techniques. abstract environment.
