This paper introduces a single-channel speech enhancement framework based on global soft-decision, where the magnitude spectrum of clean speech is estimated by combining two separate Bayesian estimators based on voiced-unvoiced uncertainty. For the voiced regions, the perceptually motivated adaptive β-order weighted minimum mean square error (MMSE)(More)
Fast growth of mobile sensing technologies, like GPS in smart phones, made capturing position data in the form of trajectories easy. But detecting anomalous trajectories, which are grossly different from remaining trajectories, is a major challenge in the surveillance domain and a big data problem. In the present work, a novel density-based method has been(More)
