Robust Feature Based Image Watermarking Process

A digital image watermarking scheme must be robust against a variety of possible attacks. In the proposed approach, a new rotation and scaling invariant image watermarking scheme is proposed based on rotation invariant feature and image normalization. The rotation invariant features are extracted from the segmented areas and are selected as reference points. Sub-regions centered at the feature ...

A Robust Digital Image Watermarking Scheme Based on DWT

In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

Robust Image Watermarking Using Feature Based Local Invariant Regions

This paper presents a novel robust image watermarking scheme for resisting geometric attacks and traditional signal processing attacks simultaneously. The proposed scheme consists of two main phases, the feature point based watermark synchronization and the Discrete Wavelet Transform (DWT) based watermark embedding/extraction. In watermark synchronization, the locally most stable feature points...
