Image steganalysis has attracted more attention recently. In this paper, a new method for detecting secret message and estimating the secret message length of bit-streams embedded using J-Steg like steganography is proposed. First, based on the model of statistical distribution of quantized DCT coefficients, the histogram of cover image is estimated from(More)
In this paper, we present a steganalytic method that can reliably detect messages hidden in JPEG images using the steganographic algorithm YASS, which is a JPEG steganographic method shown to be undetectable using current best blind steganalysis classifiers. The key element of the method is features extracted from the image's pixels and DCT coefficients.(More)
Necrotizing enterocolitis (NEC) is an often catastrophic disease that typically affects premature newborns. Although the exact etiology of NEC is uncertain, the disease is associated with formula feeding, bacterial colonization of the gut, hypoxia and hypoperfusion. In light of the pathogenesis of NEC, the integrity and function of the intestinal mucosa has(More)
