A New Method for Watermark of Color Static Image Based on Gradient Field Analysis

摘要：

The goal of this paper is to carry out a study in a new algorithm of digital watermark, which makes a information hiding calculation in spatial domain. This method can achieve a higher robustness to prevent many attacks from channel noise, JPEG, etc; and as while it can achieve a higher imperceptible than simple LSB method. The ownership insert the watermark into the host signal after analyzing the gradient of the host image based on difference method. A conclusion can be made that the proposed technique is practical.
