Quantitative analysis of quality-of-service metrics is an important tool in early evaluation of service provision. This analysis depends on being able to estimate the average duration of critical activities used by the service but at the earliest stages of service planning it may be impossible to obtain accurate estimates of the expected duration of these activities. We analyse the time-depende...

This paper proposes an iris image quality and segmentation accuracy evaluation method for videobased iris recognition systems, operating in unconstrained environment. Proposed approach consists of two stages of video quality evaluation that allows improving the iris recognition rates in non-ideal or no cooperative situations; where the first stage discards the low quality eye frames, while the ...

Analyzing large-bodies of audiovisual information with respect to discoursepragmatic categories is a time-consuming, manual activity, yet of growing importance in a wide variety of domains. Given the transcription of the audiovisual recordings, we propose to model the task of assigning discoursepragmatic categories as supervised machine learning task. By analyzing the effects of a wide variety ...
