Abstract
A novel method based on the multi-resolution transform and complex Hadamard transform to embed watermarks in grey scale digital images is proposed. Th e results show that the presented scheme is robust to JPEG compression, ima ge resizing, cropping, dithering distortion and successive watermarking eff ects.
