In this paper PQ steganography scheme is described briefly and a novel singular value decomposition (SVD) based steganalysis method is proposed to detect PQ embedding. The proposed SVD based steganalyzer detects PQ embedded relatively smooth stego images with 70% detection accuracy on average for different embedding rates.eninfo:eu-repo/semantics/closedAccessComputer scienceEngineeringImaging science & photographic technologySingular value decompositionPerturbation techniquesImage analysisEmbedded systemsData reductionSteganalysisPerturbed quantization (PQ)Embedding ratesData hidingVector quantizationProceedings Paper0002453478001052-s2.0-34247149340Computer science, artificial intelligenceEngineering, electrical & electronicImaging science & photographic technologySteganalysis; Distortion Function; Data Hiding
