A robust and secure watermarking algorithm based on DWT and SVD in the fractional order fourier transform domain
The present paper aims to develop and validate a robust and secure watermarking algorithm. Firstly, the algorithm transforms the cover image and the watermark image separately by FRFT to obtain the amplitudes of both the cover image and watermark image, and then the two-level DWT transformation only...
