Journal ArticleDOI
Reversible Watermarking Algorithm Using Sorting and Prediction
TL;DR: This paper presents a reversible or lossless watermarking algorithm for images without using a location map in most cases that employs prediction errors to embed data into an image.
Journal ArticleDOI
A Novel Difference Expansion Transform for Reversible Data Embedding
TL;DR: Performance of the proposed scheme is shown to be better than the original difference expansion scheme by Tian and its improved version by Kamstra and Heijmans and can be possible by exploiting the quasi-Laplace distribution of the difference values.
Journal ArticleDOI
No-reference image quality assessment using modified extreme learning machine classifier
TL;DR: The experimental results prove that the estimated visual quality of the proposed RCGA-ELM emulates the mean opinion score very well and indicate that the proposed schemes significantly improve the performance of ELM classifier under imbalance condition for image quality assessment.
Journal ArticleDOI
Modified patchwork algorithm: a novel audio watermarking scheme
In-Kwon Yeo,Hyoung Joong Kim +1 more
TL;DR: Experimental results show that the proposed watermarking algorithm is sustainable against compression algorithms such as MP3 and AAC, as well as common signal processing manipulation attacks.
Journal ArticleDOI
Reversible Data Hiding in JPEG Images
TL;DR: A new histogram shifting-based RDH scheme for JPEG images is proposed, in which the zero coefficients remain unchanged and only coefficients with values 1 and -1 are expanded to carry message bits, and a block selection strategy based on the number of zero coefficients in each 8 × 8 block can be utilized to adaptively choose DCT coefficients for data hiding.
