Abstract
This paper proposes a new approach in digital watermarking applications that can be adapted for embedding either fragile or robust watermarking in a digital image in the spatial domain or in the frequency domain. The main objective of the proposed scheme is to explore the amount of texture or edge pixels belonging to the host image in order to insert more information while preserving the robustness of the scheme without degrading the visual quality of the watermarked image. The host image is divided into blocks and each block can be subdivided into sub-blocks according to its texture analysis. The number of sub-blocks that each block will be divided into depends on the amount of texture or edge pixels presented by it. The numerical results show that the proposed scheme is better in JPEG compression attacks, and far exceeds others in watermark size capacity.
