However, learning from virtual-world samples and testing in real-world images may suffer the dataset shift problem. ...
Then, using such a classifier we collect pedestrian samples from real-world images by detection. After, a human oracle rejects the false detections efficiently (weak annotation). ...
Yet, the challenge consists in achieving good pedestrian detection performance with real-world images using classifiers learned from such virtual-world samples. ...

Thus, we face the question: can a pedestrian appearance model learnt in realistic virtual worlds work successfully for pedestrian detection in realworld images?. ...
Accordingly, we have designed a domain adaptation framework, V-AYLA, in which we have tested different techniques to collect a few pedestrian samples from the target domain (real world) and combine them ...
CONCLUSION In this paper we have explored how virtual worlds can help in learning appearance-based models for pedestrian detection in real-world images. ...

In this paper, we propose to train a multiview deformable part-based model with automatically generated part examples from virtual-world data. ...
The method is efficient as: (i) the part detectors are trained with precisely extracted virtual examples, thus no latent learning is needed, (ii) the multiview pedestrian detector enhances the performance ...
