Abstract
A robust image watermarking scheme relying on an affine invariant embedding domain is presented. The invariant space is obtained by triangulating the image using affine invariant interest points as vertices and performing an invariant triangle representation with respect to affine transformations based on the barycentric coordinates system. The watermark is encoded via quantization index modulation with an adaptive quantization step
