Digital Watermarking for Still Image Based on Discrete Fractional Fourier Transform
(Journal of Harbin Institute of Technology. 8 (3): 309-311 (EI)),-0001,():
A digital watermarking technique based on the discrete fractional Fourier transform (DFRFT) is proposed. The original image is transformed by DFRFT, and the DFRFT coefficients of the original image are modified by the information of watermark. Experimental results show that the proposed technique is robust to lossy compression attack.
