This paper proposes a simple method of realization of centerfrequency adaptive filters for high-accuracy detection of band-pass signals immersed in a broadband signal. Our method...
In this paper we propose a nonparametric hypothesis test for stationarity based on local Fourier analysis. We employ a test statistic that measures the variation of time-localized...
This paper addresses the problem of image retrieval from an encrypted database, where data confidentiality is preserved both in the storage and retrieval process. The paper focus...
