No-reference bit stream model for video quality assessment of h.264/AVC video based on packet loss visibility
In this paper, a no reference bit stream model for quality assessment of SD and HD H.264/AVC video sequences based on packet loss visibility is proposed. The method considers the ...

Compensation of extrinsic variability in speaker verification systems on simulated Skype and HF channel data
In this work we focus on speaker verification on channels of varying quality, namely Skype and high frequency (HF) radio. In our setup, we assume to have telephone recordings of ...

Detection of synthetic speech for the problem of imposture
In this paper, we present new results from our research into the vulnerability of a speaker verification (SV) system to synthetic speech. We use a HMM-based speech synthesizer, w...
