Iris recognition using complex valued 2D Gabor filters received a great success in broad applications. Such method encoded the iris phase information which was extracted according to the complex valued 2D filters' response. In this paper, we theoretically analyzed the complex-valued 2D Gabor filters. Based on analysis, we concluded that the real part of(More)
In this paper, we describe an effective steganalysis for four kinds of echo hiding based on combinatorial high order statistics. We analyze effect on power cepstrum, due to statistic characteristic changing with echo in stego speech. High order statistics of each segment of power cepstrum firstly are calculated, including coefficients of skewness and(More)
