Selective bit embedding scheme for robust blind color image watermarking

摘要

Highlights?A novel blind color image watermarking that uses gray-scale image as watermark.?An efficient embedding rule for wavelet coefficient difference quantization.?2D Otsu algorithm for high accuracy of watermark recovery.?A good performance balance of triangular imperceptibility-robustness-payload.?Outperformance of robustness to state-of-the-art approaches at high payload capacity.AbstractIn this paper, we propose a novel robust blind color image watermarking method, namely SMLE, that allows to embed a gray-scale image as watermark into a host color image in the wavelet domain. After decomposing the gray-scale watermark to component binary images in digits ordering from least significant bit (LSB) to most significant bit (MSB), the retrieved bi
