A New Image Hashing based on Discrete Trinion Fourier Transform
2020 8th International Conference on Digital Home (ICDH)(2020)
摘要
In this paper, a new robust image hashing scheme is proposed base on discrete trinion Fourier transform(DTFT). The key features of the present scheme rely on (i) The DTFT provides an effective way to jointly deal with the three channels of color images. (ii) The final hash is generated according to the amplitudes of these DTFT coefficients. (iii) Scrambling is applied at the last stage of hash gen...
