“Image Watermarking in Transform Domain Based on Matrix Decomposition” (9/26)
講演者 / Speaker
講演者:DHAR, Pranab Kumar (Professor, Chittagong University of Engineering and Technology)
主 旨 / Outline
Image watermarking methods using RT, FBT, DLCT, CT, JD, QRD, and 4-connected t-o’clock scrambling will be presented. A color image watermarking method based on RT and JD is proposed. Experimental results demonstrated that proposed methods show high robustness against numerous attacks. Moreover, they produce high quality watermarked images and provide high security. Furthermore, they have superior performance than recent methods in terms of imperceptibility, robustness, and security. These results indicated that the proposed methods can be effectively utilized for image copyright protection.
