A Logarithmic Quantization-Based Image Watermarking Using Information Entropy in the Wavelet Domain

A Logarithmic Quantization-Based Image Watermarking Using Information Entropy in the Wavelet Domain

Conventional quantization-based watermarking may be easily estimated by averaging on a set of watermarked signals via uniform quantization approach. Moreover, the conventional quantization-based method neglects the visual perceptual characteristics of the host signal; thus, the perceptible distortio...
