Continuous visual vocabulary modelsfor pLSA-based scene recognition

Eva Hörster, Rainer Lienhart, Malcolm Slaney
2008 Proceedings of the 2008 international conference on Content-based image and video retrieval - CIVR '08  
The performance of these continuous vocabulary models are compared in an automatic scene recognition task.  ...  Our experiments clearly show that the continuous approaches outperform the standard pLSA model.  ...  In the next section we will then present the continuous vocabulary pLSA models and explain how the scene recognition system is modified when using a continuous visual vocabulary pLSA model instead of the  ...

Erkennung visueller Konzepte in Bildern und Videos

Novel object-based features are generated based on object detection results using different pooling strategies.  ...  Due to the large complexity and variability in the appearance of visual concepts, the detection of arbitrary concepts represents a very challenging task.  ...  An audio vocabulary based on MFCC features from acoustically homogenous segments is built and the latent audio topics are discovered using pLSA.  ...
