To choose a better embedding position and strength of the digital watermark in Contourlet domain and overcome the defect that the last layer of the low frequency subband of the Contourlet transform are not divided
this paper put forward a construction method of the suppositional tree model.On this basis
combined with chaos technology
and utilizing fruit fly optimization Algorithm(FOA) to optimize the parameters of the support vector regression(SVR)
a robust and adaptive watermarking scheme is proposed.The result shows that the algorithm owns better effect on robustness
