Using robust dispersion estimation in support vector machines

N. Vretos, A. Tefas, I. Pitas
2013 Pattern Recognition  
Finally, we applied the proposed method for facial expression recognition in three well known facial expression databases, showing that it outperforms previously published attempts.  ...  Moreover, we propose a novel method for class specific multi-class SVM, which makes use of the covariance matrix of only one class, i.e., the class that we are interested in separating from the others,  ...  The matrices are constructed based on the best facial expression recognition rate for each classifier.  ...

Capture and transparency in coarse quantized images

M. Concetta Morrone, David C. Burr
1997 Vision Research  
This study examines the effect of coarse quantization (blocking) on image recognition, and explores possible mechanisms.  ...  Phase-shifting the spurious high frequencies introduced by the blocking (with an operation d~igned to leave both overall and local contrast unaffected, and feature localization) greatly improved recognizability  ...  With only one free parameter, we were able to predict with considerable accuracy the psychophysical measurements of apparent orientation.  ...

Motion analysis by feature tracking

M.Michela Del Viva, M.Concetta Morrone
1998 Vision Research  
The velocity of features is determined by the direction of maximal elongation of the energy in space-time, evaluated by calculating the three characteristic curvatures of the energy at each feature point  ...  Features are detected in each frame by locating the peaks of the spatial local energy functions, as for stationary images (Morrone MC and Burr DC. Proc R Soc Lond 1988;B235:221-245.).  ...  Acknowledgements We thank Dr David Burr for helpful discussion during this research and comments on the manuscript.  ...
