In this paper, a new class of image texture operators is proposed. We firstly determine that the number of gray levels in each B × B subblock is a fundamental property of the local image texture. Thus, an occurrence ...

In this paper, a channel selection rule for YASS (Yet-Another-Secure-Steganography) is proposed. Secret message embedding imposes distortion to the cover image. The larger the distortion, the less secure the stegano...

A novel digital watermarking scheme featuring centroid-based sectoring is proposed in this paper. To get higher robustness against geometric attacks, such as rotation, scaling, and translation (RST), a delicate sync...
