Deep VQA based on a Novel Hybrid Training Methodology [article]

Chen Feng, Fan Zhang, David R. Bull
<span title="2022-02-17">2022</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
In this context, this paper proposes a new hybrid training methodology, which generates large volumes of training data by using quality indices from an existing perceptual quality metric, VMAF, as training  ...  The resulting Deep Video Quality Metric (based on Hybrid Training), DVQM-HT, has been fully tested on eight HD subjective video databases, and consistently exhibits higher correlation with perceptual quality  ...  EXPERIMENT CONFIGURATION Training Configuration We used Pytorch 1.7 to implement both networks, with the following training parameters: L2 as the loss function; Adam optimisation [31] with hyper-parameters  ...

A computational driver model to predict driver control at unsignalised intersections

The model was optimised using data from a test-track study in which participants were asked to drive through an intersection where a cyclist would cross their travel path.  ...  The extent to which the model could be used by safety systems' threat-assessment algorithms is discussed. Future research to improve the model's performances is suggested.  ...  ACKNOWLEDGEMENTS The authors would like to thank Markus Pastuhoff, Sonny Muhoray, Peter Andersson, and Börje Jansson for setting up the test-track experiment and assisting with data collection.  ...

For our experiments, we used both impaired and unimpaired Italian speech.  ...  Specifically, we used 30 speakers with dysarthria from the IDEA database and 10 professional speakers from the CLIPS database. Both databases are freely available.  ...  Acknowledgments: The authors gratefully acknowledge initial contributions by Gabriele Meoni and Davide Mulfari from University of Pisa.  ...

<span title="2022-03-18">2022</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
biometrics has great potential for a wide range of applications since, e.g. periocular verification is contactless and is safe to use in pandemics such as COVID-19, when a major portion of a face is covered by  ...  An optimised sub-pixel convolution layer that learns a matrix of up-scaling filters to increase the final LR feature maps into the SR output was used. 4) Perceptual loss function: The ISO/IEC 29794-6  ...  From those experiments, we selected the configuration achieving the best performance. All methods were trained using the Samsung database and tested with the SET-5E dataset.  ...
