Robust Image Hashing With Singular Values Of Quaternion SVD
TL;DR: A robust image hashing with singular values of quaternion singular value decomposition (QSVD) is proposed, the key contribution is the innovative use of QSVD, which can extract stable and discriminative image features from CIE L*a*b* color space.
Journal ArticleDOI
Robust image hashing with visual attention model and invariant moments
TL;DR: The authors propose a novel image hashing with visual attention model and invariant moments that outperforms the compared hashing algorithms in classification performance between robustness and discrimination.
Journal ArticleDOI
Robust image hashing with compressed sensing and ordinal measures
TL;DR: The results illustrate that the proposed hashing method outperforms some compared algorithms in classification according to ROC (receiver operating characteristic) graph.
