Abstract

In paper [1], we present a new watermarking technique in spatial domain expressly devised for color images, which is based on transmit diversity techniques. We also show that the robustness of our new algorithm is better than single color channel. However, we don’t compare the robustness of our algorithm with luminance channel. In this paper, we describe the revised scheme of algorithm [1] in detail, and give experimental results that demonstrate the unmistakable advantage of our new approach over algorithms operating on not only single color channel, but also luminance channel. All experimental results prove that our scheme is more robust than any other single channel scheme in spatial for color images.
