Combined HVS and fuzzy control to DWT color image watermarking
Chao Gao · Journal of Beijing Information Science & Technology University · 2010
In this paper,a color image analysis and fuzzy control method is proposed which is based on HVS and fuzzy control of the DWT color image watermarking algorithm,algorithm based on the size of the watermark signal,adaptively select the original color image of the important number of wavelet coefficients,At the same time according to the characteristics of HVS to determine the watermark embedding strength,and then the fuzzy control theory to control the watermark embedding strength,will be pretreated watermark signal embedded in a certain way.Experiments prove that the algorithm is easy to implement and have a good hiding,there is a certain practical value.
