This paper investigates the finite-time filter design problem for a class of switched linear systems with parameter uncertainties and impulsive effects. The sensor failures with output-measurement errors and mode-detection delays are taken into account. A filter mode-dependent Lyapunov-like function construction approach is developed which can effectively reduce the filter design difficulty induced...
Blind steganalysis techniques detect the existence of secret messages embedded in digital media when the steganography embedding algorithm is unknown. This paper presents a survey of blind steganalysis methods for digital images. First, a principle framework is described for image blind steganalysis, which includes four parts: image pretreatment, feature extraction, classifier selection and design,...
