Journal ArticleDOI
A new robust reference watermarking scheme based on DWT-SVD
TL;DR: A new semi-blind reference watermarking scheme based on discrete wavelet transform (DWT) and singular value decomposition (SVD) for copyright protection and authenticity and it is shown that the proposed scheme also stands with the ambiguity attack also.
Journal ArticleDOI
A chaotic system based fragile watermarking scheme for image tamper detection
TL;DR: Experimental results demonstrate that the proposed chaos based watermarking scheme is not only secure but also achieves superior tamper detection and localization accuracy under different attacks.
Journal ArticleDOI
A blind watermarking algorithm based on fractional Fourier transform and visual cryptography
TL;DR: A robust copyright protection scheme based on fractional Fourier transform (FrFT) and visual cryptography (VC) and the experimental results show that the proposed scheme is strong enough to resist various signal processing operations.
Journal ArticleDOI
Local neighborhood difference pattern: A new feature descriptor for natural and texture image retrieval
TL;DR: A new image retrieval technique using local neighborhood difference pattern (LNDP) has been proposed for local features and shows a significant improvement in the proposed method over existing methods.
Journal ArticleDOI
Discrete fractional wavelet transform and its application to multiple encryption
TL;DR: A novel encryption scheme is proposed for securing multiple images during communication and transmission over insecure channel by discretizing continuous fractional wavelet transform and chaotic maps.
