Reversible data hiding for JPEG images based on histogram pairs
TL;DR: This paper proposes a lossless data hiding technique for JPEG images based on histogram pairs that embeds data into the JPEG quantized 8x8 block DCT coefficients and can obtain higher payload than the prior arts.
Book ChapterDOI
Optimum Histogram Pair Based Image Lossless Data Embedding
TL;DR: An optimum histogram pair based image lossless data embedding scheme using integer wavelet transform and adaptive histogram modification can achieve the highest visual quality of marked image for a given payload as compared with the prior arts of image lossed data hiding.
Proceedings ArticleDOI
JPEG Steganalysis Based on Classwise Non-Principal Components Analysis and Multi-Directional Markov Model
TL;DR: The experimental results have demonstrated that the proposed scheme outperforms the existing steganalysis techniques in attacking modern JPEG steganographic schemes-F5, Outguess, MB1 and MB2.
Book ChapterDOI
A Novel bayesian classifier with smaller eigenvalues reset by threshold based on given database
TL;DR: A novel Bayesian classifier with smaller eigenvalues reset by threshold based on database is proposed in this paper, and the error rates of both handwritten number recognition with MNIST database and Bengali handwritten digit recognition are small by using the proposed method.
