Owing to the ever proliferation of digital cameras and image editing software, a large variety of JPEG quantization tables are used to compress JPEG images. As a result, learning-based steganalysis methods using a pre-selected quantization table for training images degrade significantly when the quantization table of testing images is different from the one(More)
Pattern classifiers have been widely used in adversarial settings like spam and malware detection, although they have not been originally designed to cope with intelligent attackers that manipulate data at test time to evade detection. While a number of adversary-aware learning algorithms have been proposed, they are computationally demanding and aim to(More)
Researched the mix proportion of using self-made high-performance sludge ceramic to prepare LC40 LWAC. Studied the effect of ceramic-size, supplementary cementitious materials, water-cement ratio and sand-ratio on the LWAC performance. The study shows, size of ceramic too large can cause strength decrease, poor stability and workability; supplementary(More)
