In this paper, we present a high-capacity watermarking scheme for color images by using the idea of L2-Norm centroid. Based on spatial domain, the proposed scheme can effectively embed a secret watermark in a host image. Simulations demonstrate that the marked images generated by the proposed watermarking scheme are tolerant of versatile attacks such as color reduction, compression, cropping, blurring,...
In this paper, we propose a watermarking scheme with high perceived quality for color images by using the Euclidean distance of radius-weighted mean (RWM) and centroid. Based on spatial domain, the proposed watermarking scheme can effectively embed a secret message in host images. Simulations demonstrate that the marked images generated by the proposed watermarking scheme are tolerant of versatile...
Based on integer wavelet transform (IWT), the author uses the idea of radius-weighted mean (RWM) and present a high-capacity color image watermarking scheme. More specifically, the Euclidean distance of RWM and centroid is used as the embedding criterion, a watermark is hidden in the low-low (LL) subbnad of IWT domain. To further promote payload size, the criterion of Euclidean norm of RWM is employed...
A so-called DHCED (Data Hiding by Conjugate Error Diffusion) method was proposed to hide a binary visual secret into halftone images such that the watermarked halftone image still has good visual quality. When decoding, the secret can be visually revealed by directly superimposing the halftone images. The authors claimed that the DHCED scheme reduced the boundary artifacts around the hidden visual...
