Comments Off on Reversible Image Data Hiding with Contrast Enhancement
Posted in: IEEE 2017, MATLAB
Reversible Image Data Hiding with Contrast Enhancement ABSTRACT: In this letter, a novel reversible data hiding (RDH) algorithm is proposed for digital images. Instead of trying to keep the PSNR value high, the proposed algorithm enhances the contrast of a host image to improve its visual quality. The highest two bins in the histogram are […]

Comments Off on Revealing the Trace of High-Quality JPEG Compression through Quantization Noise Analysis
Posted in: IEEE 2017, MATLAB
Revealing the Trace of High-Quality JPEG Compression Through Quantization Noise Analysis ABSTRACT: To identify whether an image has been JPEG compressed is an important issue in forensic practice. The state-of-the-art methods fail to identify high-quality compressed images, which are common on the Internet. In this paper, we provide a novel quantization noise-based solution to reveal […]
