Liu, Dong; Wang, Shengsheng; Porikli, Fatih


Appearance-based bag-of-visual words (BoVW) models are employed to represent the frequency of a vocabulary of local features in an image. Due to their versatility, they are widely popular, although they ignore the underlying spatial context and relationships among the features.

First, we use a...[Show more]
